Paul’s a worrier, a panicker, the neurotic nice guy who always finishes last, but never stops trying. His twenties were supposed to be awesome, but so far the most exciting thing that's happened is his girlfriend, Claire, agreeing to move in. And even that looks set to be a disaster, with his freewheeling parents hell bent on becoming bezzie mates with them, and Claire's hot ex Greg back on the scene, intent on reliving wild tales of their sexual past. Will prudish Paul lose the girl of his dreams to Greg and his endless abs, or can he convince her that he's just as sexually daring?
