Holt McCallany plays Patrick "Lights" Leary, an ex-heavyweight champ who's scrambling to support his wife, Theresa (Catherine McCormack), a medical resident, and their three daughters. The series opener begins five years after Lights' retirement (at Theresa's insistence) following a controversial split-decision loss. The Learys live in a mansion, but he's going broke, and the IRS is after him and his manager-brother (Pablo Schreiber). Lights is also showing signs of "pugilistic dementia."
