Irishman Brogan Byrne is at the pinnacle of rock music success in 1974. Handsome, charismatic, with a three-octave voice, you’d think he had it all. But Byrne sinks to new depths of depravity with women, liquor, and drugs. Carly Montgomery is an ambitious record executive offered an opportunity to be manager for the last leg of Byrne's tour. Though she's detached and tough as nails, Carly's cool facade comes under attack. Somehow Byrne manages to slip by her frosty defenses. Brogan, for his part, is broken inside. A memory weighs on his soul and affects his actions. Is Carly the one woman to help him forget his guilt and heal his heart of rock?
