The Saint of Fort Washington (1993)

In New York City, Jerry (Danny Glover), a homeless, street-smart Vietnam veteran, befriends Matthew (Matt Dillon), a mentally ill young man who has recently been kicked out of his home. As Jerry teaches Matthew how survive as a homeless person, the two split time between the streets and a shelter, where they're viciously bullied by Little Leroy (Ving Rhames). As their friendship strengthens, the two plan to save enough money to rent an apartment.
