Kind of a sequel to the Deadly Assassin. The Doctor and Leela end up on Gallifrey, as the Doctor seems to have made a deal with the Vardan race to invade the homeworld of the Time Lords. The Doctor becoming President this time as he once threw his name in for consideration. Episodes 1 to 4 are good, but once the Sontarans turn up I ep 5 it just seems too much. Leela's exit is a bit naff too.
