Pat (Bradley Cooper - scary but completely winning) lost it when he found his wife in the shower with another teacher. He beat the guy up so badly that he avoided jail only by a plea-bargain, accepting long-term treatment in an institution for his previously undiagnosed bipolar disorder — his estranged wife taking out a restraining order against him none the less. Having lost his job, his wife and his home, Pat comes home after eight months to live with his sports-mad, amateur bookie OCD dad, Pat Sr (Robert de Niro) and hopeful Mom (Jacki Weaver).  He’s convinced that if only he works at it enough, he can win his wife back Then he meets Tiffany (Jennifer Lawrence). Tiffany, recently widowed, is at least as mad as Pat, neither of them having any filter on what they say or do.
