Vicki and Troilus are on the move. Having escaped from the fall of Troy, they and their people have been wandering in search of a place to settle. The Doctor is trying to get Wilf back home. The TARDIS dematerialises, and he thinks they've arrived in Stratford-upon-Avon in 1572, but it turns out they've arrived in ancient Asia Minor. The Doctor is making plans too. He wants Charley to get Wilf drunk so that he won't remember anything the next day. As they are all enjoying the wine, Vicki's people attack. Vicki in particular attacks the Doctor, trying to find the wires controlling him.
