Susan is hanging out in a bar during a poetry recital and sees a man mutating into an alien life form. When she tells her grandfather, he decides they must investigate. They find a secret laboratory below the tube tunnels in central London. An alien called Raldonn is carrying out mutagentic experiments to create a pilot of a genetic make-up similar to himself to assist in flying his ship.
