SUSAN: Oh, don't blame yourself, Grandfather. DOCTOR: (Noticing something.) Look at those, look at them... (A skull lies next to them...with a hole smashed in at the top of its head....) IAN: Yes, they're all the same. They've been split wide open... [SCENE_BREAK] 2: INT. MAIN CAVE (Late night. The entire tribe is asleep. Tribes-men and women are piled on furs and blankets, lying next to each other for precious warmth. One stirs - the OLD MOTHER. She gets up, looks around, and slowly sneaks toward the sleeping ZA. She leans down and takes his sharp stone knife.) [SCENE_BREAK] 3: INT. CAVE OF SKULLS (IAN is using one of the many small rocks on the floor to try and saw away at BARBARA'S binds. SUSAN crawls over to him, carrying another rock.) SUSAN: I've found another piece with a rough edge... IAN: (Eases off with a sigh of relief and takes the rock.) Oh, thank you.

Even if we do get free, we shall never move that stone. IAN: (Scanning the cave with his eyes.) There's air coming in here from somewhere... BARBARA: (Excited.) Yes, there is! I can feel it on my face! IAN: It may only be a small opening. Don't count on it... DOCTOR: Oh, you obviously are. IAN: Well, of course I am! Any hope is better than none! Don't
SUMMARY:
Barbara Wright and Ian Chesterton, two humble teachers during 1963, are surprised by a bright student named Susan Foreman. Feeling inquisitive of her upbringing, they seek out her residence to learn who nurtured such a genius. There, they discover a junkyard inhabited by her grandfather, simply known as "the Doctor", and he doesn't want them lurking about. When the teachers refuse to leave, they discover that an ordinary police box is actually bigger on the inside. The Doctor decides they know too much about his and Susan's otherworldly origins and takes them on a journey across space and time in his TARDIS, the place he and Susan now call home.
