Who's wearing the trousers?

Trevor is a present day, happy go lucky guy in his thirties, who lives with his relatively quiet girlfriend, Jane. Following a knock on the head, things around him seem somewhat strange. Unperturbed, he carries on his normal life, until he realises that his recent bang on the head has placed him in a different dimension, one where women are the dominant sex. Although concerned about the situation, he continues to live the way that he has been used to, often with comical results.
