Mobster and hit man Jimmy Conlon has one night to figure out where his loyalties lie: with his estranged son, Mike, whose life is in danger, or his longtime best friend, mob boss Shawn Maguire, who wants Mike to pay for the death of his own son.
Haunted by the ghosts of his past, former Irish mob enforcer Jimmy “The Gravedigger” Conlon has become an angry drunk, unable to connect with his son Michael (Mike), a retired professional boxer who mentors at-risk kids at the local gym. Disgusted by his father’s actions, Michael refuses to involve him in the lives of his daughters, Catelyn and Lily.
Jimmy’s old boss and closest friend, Shawn Maguire, rejects an offer to sell Albanian heroin. His son Danny, who received a large fee to arrange the deal, is told to return the money or suffer the consequences.
Mike, moonlighting as a chauffeur, takes the Albanian creditors to Danny’s house. He witnesses Danny kill them and flees, but accidentally drops his wallet and ID.
