"You have been cheated by the false Outsider. The Doctor is no enemy"
A strange signal from Earth draws the TARDIS to the island of Lanzarote, where Turlough rescues a young American girl, Peri, from drowning. Among her possessions is an artifact bearing an alien symbol — the same triangular mark that Turlough has branded into his arm. The mystery deepens when Kamelion falls under the control of a powerful mind, and the TARDIS travels to the volcanic world of Sarn. As Turlough is forced to face his past, the Doctor must stop his oldest enemy from harnessing the revitalizing powers of Numismaton gas.
