“It’s not me that scares you... it’s the world!”

Nicky Henson is Tom, the leader of a motorcycle gang called The Living Dead, who terrorise the Home Counties and hang around some standing stones called The Seven Witches.

His mum is Beryl Reid, a medium, whose butler appears to be some kind of emmissary for the devil.

Tom would rather hunt for frogs than be with Abby, his girlfriend. She's understandably unhappy: "Tom... you're not human! Sometimes you scare me!"

Tom thoughtfully replies "It's not me that scares you... it's the world!" and then puts forward his theory about coming back from the dead, which is half-baked, to say the least. If it was that easy, surely everyone would be doing it?

Back home, after delivering the frog, he asks his mum's butler, Shadwell:"Why did my father die in that locked room? Why do you never get any older? And what is the secret of the living dead?"

He then has a bit of a dance with his mum in her cool 70s pad, before she allows him access to said locked room, where he puts on a pair of unfashionable spectacles, loses his reflection (careless) and sees his life in flashback... all of it connected to those standing stones...

This seems to help Tom come to a decision, and he takes his gang on a destructive spree - driving fast through floods, ignoring road works, kicking over cones, tidying up shopping carts and stealing brollies. Real hell's angels stuff.

At the end of this he does "the ton" on his bike, crashes off a bridge and dies. The gang bury him upright on his bike, and he comes screaming back to life a couple of days later, then starts bumping off the local populace and convincing his gang that in order to come back from the dead, you only have to believe you will. And they believe him!

The body count in this film is huge - gang members bump themselves off and kill what must amount to most of the town, including every policeman who gets in their way.
