The true story of Troy Duffy, a brash, foul-mouthed bartender whose screenplay for an action film (Boondock Saints) scores him a generous contract to write and direct the film at Miramax Studios. Duffy's band, the Brood, is also in the midst of signing a contract with Madonna's Maverick Records. Duffy's fiery manner is instrumental to his success, but when the deals go sour, no one seems safe from his explosive temper.
