Two agents are dead, and their murderers sound worryingly familiar. A
killer gorilla is on the loose, a deadly disease is ravaging a distant
country and an eminent doctor has been kidnapped. It's all pretty much
business as usual.
But when John Steed is called in by his old boss and given an appalling
task to complete, at the same time as Tara is given one that's even
worse, it becomes clear that the myriad threads of a terrifying scheme
are drawing together. The fate of the world hangs in the balance.
Steed won't be able to handle this case alone.
The Avengers are needed. All of them.
