The Prince of Tides (1991)
From Wikipedia: Tom Wingo (Nick Nolte), a teacher and football coach from South Carolina, is asked by his mother, Lila, to travel to New York to help his twin sister's psychiatrist, Susan Lowenstein (Barbra Streisand), after his sister Savannah's (Melinda Dillon) latest suicide attempt. Despite hating New York City, Tom reluctantly accepts but does so in large part to take the opportunity to be alone and away from a life that does not satisfy him. During their initial meetings, Tom is reluctant to disclose many details of their dysfunctional family's secrets. In flashbacks, Tom relates incidents from his childhood to Lowenstein, in hopes of discovering how to save Savannah's life. The Wingos were a family composed of an abusive father and an overly proud, status-hungry mother. The father was a shrimp boat operator and, despite being successful at that profession, spent all of his money on frivolous business pursuits, leaving the family in poverty. Tom is also torn with his own problems, but hides behind what he calls "the Southern way"; e.g., laughing about everything.
