Nicholas Van Orton, a wealthy investment banker, is estranged from both his ex-wife and his younger brother, Conrad. He remains haunted from having seen his father commit suicide on the latter's 48th birthday. For Nicholas's own 48th birthday, Conrad presents Nicholas with an unusual gift—a voucher for a "game" offered by a company called Consumer Recreation Services (CRS). Conrad promises that it will change his brother's life.
Nicholas has doubts about CRS, but he meets fellow bankers who enjoyed the game. He goes to CRS's offices to apply and is irritated by the lengthy and time-consuming series of psychological and physical examinations required. He is later informed that his application has been rejected. Soon Nicholas begins to believe that his business, reputation, finances, and safety are at risk. He encounters a waitress, Christine, who appears to have been endangered by the game. Nicholas contacts the police to investigate CRS, but they find the offices abandoned.
