00:00:05.280 seconds
The blue police-box shape of the TARDIS rushes forward through the space-time vortex.
2
00:00:10.590 seconds
The Doctor's face, wide eyed and curly haired, forms in the tunnel of onrushing light; then is replaced by the words DOCTOR WHO in a diamond-shape logo.

00:00:02.000 seconds
The Sontaran Experiment.

00:00:02.000 seconds
By Bob Baker and Dave Martin.

00:00:02.000 seconds
Part 2.
6
00:00:02.449 seconds
Roth and Sarah are held captive.
7
00:00:03.000 seconds
A powerful, squat figure emerges from the ship.
8
00:00:03.000 seconds
The figure wears flexible metallic armour with a dome shaped helmet.
9
00:00:03.000 seconds
It removes its helmet from the wide locking collar.
10
00:00:03.000 seconds
Underneath are the lumpy, troll-like features of a Sontaran!
11
00:00:05.680 seconds
Harry watches from cover as the Sontaran stalks toward Sarah and looms over her.
12
00:00:04.130 seconds
He grasps Sarah’s neck, scrutinising her features.
13
00:00:06.240 seconds
Releasing her, he taps a device on his belt. The cords retract into the robots carapace, freeing Roth and Sarah.
14
00:00:02.099 seconds
[FAST] Styre speaks into a device.
15
00:00:03.000 seconds
Panicking, Roth runs. The Sontaran shoots him.
16
00:00:03.000 seconds
Roughly, he examines Sarah again.
17
00:00:02.019 seconds
Harry slips quietly away.
18
00:00:04.440 seconds
The ravine. The Doctor is trying to climb the steep slope using a tree branch.
19
00:00:03.710 seconds
The three Galsec men stand at the top, weapons drawn.
20
00:00:02.089 seconds
Harry explores the rocks.
21
00:00:06.330 seconds
He discovers a man wearing a GalSec uniform manacled to the rocks. He’s bearded, emaciated and dirty.
22
00:00:03.000 seconds
Harry examines him clinically, checking his eyes.
23
00:00:04.850 seconds
The ravine. The doctor hauls himself slowly and carefully up over the edge.
24
00:00:01.269 seconds
[FAST] The Doctor looks past him.
25
00:00:03.380 seconds
The silver, insect-like robot, comes up behind the men.
26
00:00:04.210 seconds
Surprised, they turn, and unleash a barrage of blaster fire.
27
00:00:05.370 seconds
But the Robot is immune to their weapons and advances on them. They are trapped between the robot and the ravine.
28
00:00:04.360 seconds
The cords whip out and catch Krans, then Vural, then Erak, pinning their arms.
29
00:00:03.700 seconds
At the rocks, Harry puts a wet cloth into the manacled mans mouth.
30
00:00:05.830 seconds
Weakly, the man sucks the water. Harry tugs ineffectually at the manacles.
31
00:00:03.000 seconds
Harry removes the cloth so the man can speak.
32
00:00:03.000 seconds
He mops the mans brow with the cloth.
33
00:00:02.189 seconds
The man nods weakly.
34
00:00:05.530 seconds
The ravine. The Doctor explores, working his way along the rocks and checking the tangled vegetation.
35
00:00:03.440 seconds
He discovers the cave entrance and sniffs at it.
36
00:00:03.000 seconds
He brushes back the foliage and crawls inside.
37
00:00:01.739 seconds
[FAST] Elsewhere among the rocks.
38
00:00:02.529 seconds
Sarah is sitting, manacled to a rock-face.
39
00:00:01.890 seconds
Styre licks his lips
40
00:00:03.590 seconds
Styre takes a device from his belt and presses a button.
41
00:00:04.160 seconds
He then stalks away throught a gap in the rocks.
42
00:00:02.469 seconds
Sarah tests her bonds.
43
00:00:03.900 seconds
Nearby, Harry, now equipped with a stout branch, jumps from rock to rock.
44
00:00:03.000 seconds
He sees Styre coming and takes cover.
45
00:00:05.800 seconds
He crouches behind an edifice of lichen-encrusted rock, branch held ready.
46
00:00:02.920 seconds
The Sontaran moves off in another direction.
47
00:00:06.440 seconds
In the cave, the Doctor squeezes through the narrow gap, and then emerges, wide-eyed, into the daylight.
48
00:00:03.000 seconds
He sets off towards the weathered granite outcrop.
49
00:00:02.069 seconds
Harry explores the rocks.
50
00:00:05.310 seconds
He bounds over the boulders and finds her, sitting, strapped to a rock face.
51
00:00:01.979 seconds
Harry recoils in pain.
52
00:00:03.000 seconds
He pushes his hands ineffectively against thin air.
53
00:00:03.320 seconds
Nearby, the Doctor climbs up the rocks.
54
00:00:05.280 seconds
Elsewhere among the rocks, Styre operates controls on a yellow globe with an inset screen.
55
00:00:04.250 seconds
He terminates the communication and speaks into his recording device.
56
00:00:02.369 seconds
Styre operates a control.
57
00:00:03.000 seconds
On the monitor, Sarah is waiting for Harry to return.
58
00:00:07.450 seconds
On her forehead is an alien device, a white oval, lined with red veins, with a metal protuberance like an extruded metal cog.
59
00:00:03.000 seconds
Her eyes suddenly notice movement down and to her left.
60
00:00:04.070 seconds
A snake, mottled green and brown, wraps its coils around her wrist.
61
00:00:03.620 seconds
Sarah shudders, but forces herself to look away.
62
00:00:03.900 seconds
When she looks back, there is no snake, just the ropes binding her wrist.
63
00:00:01.539 seconds
She looks up.
64
00:00:06.620 seconds
The top of the cliff looms over her. It seems like the boulders may topple at any time.
65
00:00:07.060 seconds
Now, the ground at her feet softens into thick, gelatinous mud. It heaves and swallows her legs ...
66
00:00:05.610 seconds
She is paralysed, eyes wide with fear, gasping for air, as it oozes higher, and higher ...
67
00:00:05.340 seconds
He burns out the forcefield generator in the rock with his sonic-screwdriver, and snatches the device from her forhead.
68
00:00:03.000 seconds
Sarah falls unconscious. The Doctor cradles her head.
69
00:00:02.830 seconds
[FAST] Styre emerges from a passage between the rocks.
70
00:00:02.170 seconds
[FAST] Styre swats the Doctor away.
71
00:00:01.789 seconds
He draws his gun.
72
00:00:02.389 seconds
Styre spins, but it’s a trick! The Doctor shoves him.
73
00:00:01.350 seconds
Styre raises his gun.
74
00:00:03.020 seconds
The Doctor dodges and runs. Styre adjusts his aim.
75
00:00:01.109 seconds
The Doctor falls.
76
00:00:04.970 seconds
Later, the robot drags the three GalSec men to the Sontaran space-craft
77
00:00:04.790 seconds
The door in the spherical craft opens and Styre emerges.
78
00:00:03.430 seconds
Styre stalks down the slope from his ship toward them.
79
00:00:03.360 seconds
Now at the rockface, Harry examines the unconscious Sarah.
80
00:00:01.829 seconds
Troubled, he gets up.
81
00:00:03.750 seconds
He nimbly jumps down and across the boulders to the body.
82
00:00:04.460 seconds
Seething, he grasps his heavy branch and stalks away to check on the galsec man nearby.
83
00:00:03.850 seconds
The pale man is unresponsive. Harry checks for a heartbeat.
84
00:00:03.090 seconds
Harry quickly takes cover, pressing himself against a rock-face.
85
00:00:04.680 seconds
Styre, still not wearing his helmet, emerges from a dark passage between the rocks.
86
00:00:02.219 seconds
He approaches the Galsec man.
87
00:00:04.380 seconds
The troll-like Sontaran roughly examines him.
88
00:00:03.000 seconds
He speaks into the wedge-shaped device.
89
00:00:05.000 seconds
Harry, gripping his club tightly, sneaks up on Styre as he dictates.
90
00:00:03.000 seconds
But before he can strike a hand clamps over his mouth.
91
00:00:03.000 seconds
It is the Doctor, who leads him quietly away.
92
00:00:01.350 seconds
He throws it away.
93
00:00:04.350 seconds
Leaving Harry, the Doctor clambers up the blocky granite boulders.
94
00:00:03.000 seconds
He makes his way along the top of the outcrop.
95
00:00:02.119 seconds
Meanwhile, Styre begins a new experiment.
96
00:00:05.860 seconds
Vural is lying shackled to a rock. Erak and Krans hold each end of a flattened bar above him.
97
00:00:03.231 seconds
Erak and Krans struggle with the bar as it changes weight.
98
00:00:03.940 seconds
Forced to their knees, they struggle to stop it crushing Vural.
99
00:00:05.630 seconds
The Doctor meanwhile warily approaches the iron-grey globe of the Sontaran space ship nestled in the rocks.
100
00:00:03.000 seconds
Alerted, the robot approaches and scans him.
101
00:00:02.759 seconds
Calmly he holds up his sonic-screwdriver.
102
00:00:05.161 seconds
The robot shudders, its articulated legs collapsing awkwardly, its head waving too and fro.
103
00:00:01.889 seconds
He looks towards the distant cry.
104
00:00:01.789 seconds
They struggle with the gravity bar.
105
00:00:03.000 seconds
The bar returns to normal and they lift it clear of Vural.
106
00:00:02.279 seconds
Styre stalks angrily away.
107
00:00:04.390 seconds
Erak strains against his bonds to reach his machete laying discarded nearby.
108
00:00:03.000 seconds
Styre meanhwile is at the communicator in the rocks.
109
00:00:01.739 seconds
Hidden, the Doctor eavesdrops.
110
00:00:02.119 seconds
The Doctor slips quietly away.
111
00:00:01.409 seconds
Later:
112
00:00:02.490 seconds
He takes Harry’s stout branch.
113
00:00:02.539 seconds
Styre has resumed his sadistic experiment.
114
00:00:03.000 seconds
Styre throws his gun down and grabs Erak’s machete.
115
00:00:01.859 seconds
The Doctor jumps down.
116
00:00:05.101 seconds
Styre lunges with the machete, but the Doctor parries and lands a blow as Styre stumbles into the rock face.
117
00:00:04.320 seconds
Styre spins and takes wild swipes, but the Doctor defensively guards himself with the branch.
118
00:00:04.910 seconds
The Doctor grins, goading Styre. Styre strikes again, and misses. The Doctor whacks Styres arm.
119
00:00:04.880 seconds
Meanwhile, Sarah and Harry rush in to help Erak and Krans lift the gravity bar from Vurals chest.
120
00:00:04.840 seconds
Styre, on the offensive, chases the Doctor, who climbs to higher ground on the giant boulders.
121
00:00:03.000 seconds
Harry now scrabbles over the rocks toward the Sontaran Space ship.
122
00:00:03.000 seconds
Styre, growing more enraged, strikes wildly at the Doctor and misses.
123
00:00:05.080 seconds
Meanwhile, Harry, armed with the Doctor’s sonic-screwdriver, points it at the Sontaran ship.
124
00:00:01.769 seconds
The door swings open.
125
00:00:04.560 seconds
Meanwhile, Styre's movements are increasingly laboured, his blows erratic.
126
00:00:04.440 seconds
The Sontaran staggers away, but the Doctor leaps from above, knocking him down.
127
00:00:05.210 seconds
They wrestle, but the powerful alien easily shrugs off the Doctors attack, and raises the machete.
128
00:00:03.000 seconds
Vural runs down the slope, followed by Erak and Krans.
129
00:00:04.331 seconds
He grabs the Sontarans arm. Styre turns and lands a lethal blow on Vurals neck.
130
00:00:04.340 seconds
Once again, the Doctor launches himself at Styre, knocking him to the ground.
131
00:00:03.000 seconds
Harry leaves the ship, carrying a mechanical component.
132
00:00:03.390 seconds
Using the Doctor's momemtum, Styre flips the Doctor over and throws him to the ground.
133
00:00:03.000 seconds
He staggers away, towards his ship.
134
00:00:03.000 seconds
With laboured steps he staggers into his ship.
135
00:00:03.000 seconds
The three of them run and take cover behind a boulder.
136
00:00:05.960 seconds
Smoke billows from the Sontaran scout ship, and Styre emerges, staggering, clutching the back of his neck.
137
00:00:01.639 seconds
He falls awkwardly.
138
00:00:07.520 seconds
As they watch, his golem-like face crumples like a balloon with the air let out, the tissues within collapsing.
139
00:00:03.439 seconds
The ship explodes in a magnesium white flash.
140
00:00:04.000 seconds
Sarah peeps up from behind a rock.
141
00:00:02.449 seconds
Then Harry and the Doctor.
142
00:00:05.440 seconds
Later, the Doctor finds Styres communication module, nestled in the rocks, and operates a control.
143
00:00:02.000 seconds
He grins, cat like.
144
00:00:03.890 seconds
At the transmat station, the Doctor, Sarah and Harry prepare to leave.
145
00:00:03.980 seconds
Erak and Krans step back to the edge of the circle.
146
00:00:02.290 seconds
The three dissapear …
147
00:00:02.000 seconds
… and he's gone.
