Colonel Manning (Glenn Langan) somehow survives a close-by nuclear test blast and begins to grow, he becomes an (amazing) colossal man. Unfortunately his brain has also been affected and he becomes very dangerous, and hungry. Egged on by his wife Carol (Cathy Downs), the US military don't just try and kill him. Though when Manning escapes he begins a rampage across Los Angeles.
Yet another giant mutated creature causes havoc, shown using some ropey cheap special effects. For a change the monster is human and not a giant insect or spider. This is a campy film with a big helping of cheese.
It is nonsense and fairly entertaining though Manning spends a good deal of the film groaning and moaning and it does get a bit tedious after a while.
