John Smith (Danny Dyer) has been happily involved in a bigamous marriage for five years. He lives with Stephanie (Sarah Harding) in Finsbury and Michelle (Denise Van Outen) in Stockwell. Fortunately, for John, he’s a taxi driver which involves varying shift work. Simple? Well, when John unwittingly becomes a have-a-go hero and the Finsbury and Stockwell Police forces discover something suspicious in their paperwork, John’s happy bubble is about to be burst. The action of the movie takes place during the next hectic twenty-four hours as John, with the assistance of his gullible neighbor Gary Gardner (Neil Morrissey), rush between North and South London attempting to thwart the Police and prevent the two loving wives from coming face to face.
