Some weird vulture people team up with some woman from UNIT and tell Sarah Jane that the Doctor is dead. These vulture people are like undertakers, BRAVO DAVIES! and are supposed to be in charge of the funeral, I think. Then Sarah Jane, Jo Grant and some other people figure out that these vultures are lying and that the Doctor is alive, and then the Doctor swaps places with one of the characters and the vultures try to kill him. I really don't know, I haven't watched the full episode, or the series in general...
