Fading charmer Tommy Wilhelm has reached his day of reckoning and is scared. In his forties, he still retains a boyish impetuousness that has brought him to the brink of chaos: he is separated from his wife and children; at odds with his vain, successful father; failed in his acting career (a Hollywood agent once placed him as "the type that loses the girl"); and in a financial mess. In the course of one climactic day he reviews his past mistakes and spiritual malaise, until a mysterious, philosophizing con man grants him a glorious, illuminating moment of truth and understanding and offers him one last hope.
