In Gene Wilder and Richard Pryor's fourth film, George (Wilder) is a pathological liar whose transition from a mental hospital to the outside world is to be assisted by Eddie (Pryor), a con man who has talked his way out of a jail term by agreeing to do community service. In fact Eddie plans to ditch George, but when a passerby mistakes George for a missing billionaire, Eddie persuades him to employ his facility for fabrication, and become "another you." After spending years trying not to lie, George suddenly gives his lying skills full rein, fooling everyone including the sexy Elaine (Mercedes Ruehl), the wife he has just inherited. Eddie, meanwhile, pursues his own romantic interests - the beautiful Gloria (Vanessa Williams). But all is not what it seems. The scam artists are being double-scammed, and George is in grave danger.
