The TARDIS lands on Earth circa 40000 BC. The Doctor and Turlough head for a rise in terrain, below which they can see a tribe of Cro-Magnons. The Doctor hopes to observe the first contact between Neanderthals and Cro-Magnons. He has spent much research into finding the correct moment, and has narrowed it down within six months. Turlough is amazed at the prospect of observing for six months. The Doctor suggests he take the TARDIS and jump ahead six months so he won't have to wait with the Doctor. As Turlough heads back to the TARDIS, the Doctor sets up his surveillance equipment.
