Disgraced TV presenter Martin Sharp, the lonely housewife Maureen (51 years old), the unsuccessful musician JJ and the rude teenager Jess (18 years old) meet at Toppers' House in London on New Year's Eve. They all want to commit suicide by jumping from the roof. Their plans for death in solitude, however, are ruined when they meet. After telling their individual stories to the others, they decide to hold off on jumping and to help each other. Thus a group of four unfortunate and very individual people forms. Jess's condition not to jump is that they help her to find her ex-boyfriend Chas. So they take a taxi and drive to the party they suppose Chas to be at. After finding and talking to Chas they decide to go to Martin's place where they find Penny, who has obviously been crying. She accuses Martin of cheating on her because he had left the party they'd both attended that evening without any explanation.
