Social science fiction with a sprinkling of humour. Gay to straight or straight to gay? The story was that some scientists in Edinburgh had carried out experiments on mice. When the scientists gave a large dose of insulin to the mice in their food, a number of the mice began to engage in same-sex sexual activity. Would you change your sexual orientation if you could? How does sexuality and sexual orientation actually work? These are the questions facing a group of young people living in the North of England. Along the way, they confront issues of sexual role, family breakdown, social isolation and what's going on in John's fridge - you name it.
