Nick Cameron, serving time for a crime he didn't commit, is chosen for experiments for suntanning lotions. What he doesn't realise is that there's a hidden agenda and it's only until he touches water that he finds what the experiment really is.
The head of the original Gyges project is now confined to a lunatic asylum, having been made permanently invisible, he's gone insane. Ms Jefferies is lying low, while Moreau and Dr Connor face a desperate race to find a cure for the Head. A cure which Nick can help with, if only they could find him.
