The Saint of Fort Washington (movie, 1993)

Matthew, a young schizophrenic, finds himself out on the street when a slumlord tears down his apartment building. Soon, he finds himself in even more dire straits, when he is threatened by Little Leroy, a thug who is one of the tough denizens of the Fort Washington Shelter for Men. He reaches out to Jerry, a streetwise combat veteran, who takes Matthew under his wing as a son. The relationship between these two men grows as they attempt to conquer the numbing isolation of homelessness.
