Joe and Betty are a middle-aged married couple leading a monotonous, emotionally stagnant existence running a small, independent retail fish market in Jersey City. While Joe is completely consumed by the exhausting, early-morning grind of his trade, Betty grows increasingly resentful of his neglect and his refusal to sell the business to modern real estate developers. Their predictable world is upended when Nick, a young, homeless drifter on the run from the law, stumbles into their shop. Taking pity on the boy, Joe offers him room and board in the vacant bedroom of their estranged adult son, Danny, who left for Hollywood to pursue comedy. Nick quickly adapts, becoming a devoted surrogate son to Joe at work—but at home, his presence awakens Betty's long-dormant desires, igniting a passionate, secret affair. The volatile arrangement implodes when a bitter, failing Danny unexpectedly returns home with his new family. Sensing the suffocating web of deception, Danny's jealousy pushes the household toward a dark, explosive confrontation that strips away every layer of loyalty and forces them to face the lethal cost of their hidden passions.
