Lights Out follows the struggles of retired professional boxer Patrick "Lights" Leary (Holt McCallany) -- a former heavyweight champ turned full-time familyman who once had $12 million in the bank, but now owes the IRS seven figures thanks to a sobering recession, his manager brother's (Pablo Schreiber) shady dealings, and his father's (Stacy Keach) prized boxing gym. The way Lights sees it, the only way to pay back his debts and provide for his wife (Catherine McCormack) and daughters (Meredith Hagner, Ryann Shane, and Lily Pilblad) is to re-enter the ring after a five-year absence. But doing so at 40 is a serious gamble.
