A space freighter hijacked by Cybermen was thrown back in time to approx 66 Million BC. Adric, a companion of the time traveling alien known as the Doctor, refused to leave the ship when the humans regained control because he was attempting to keep the ship from crashing into the Earth. Adric almost completed his task when a near death Cyberman shot the computer making the boy’s task impossible to complete. Meanwhile the Doctor and his companions defeated the Cyber-Leader holding them captive on the Doctor’s ship the TARDIS but not in time to save Adric as the ship he was on collided with the Earth causing the extinction of the dinosaurs.
