In the small town of Millbrook, Tom Stall (VIGGO MORTENSEN) is an easygoing diner owner, husband to lawyer Edie (MARIA BELLO) and father to young Sarah (HEIDI HAYES) and her teenage brother Jack (ASHTON HOLMES) who has problems being picked on by high school bully Bobby (KYLE SCHMID). Tom's life forever changes when two murderous thugs enter his diner looking for trouble. With surprising efficiency, Tom easily thwarts their efforts, violently killing them.
His actions make him a local hero, but they also draw the attention of Philly mob figure Carl Fogaty (ED HARRIS) who arrives in Millbrook soon thereafter with his thugs in tow. Fogaty acts like he knows Tom, calls him Joey and informs him that another mob boss, Richie Cusack (WILLIAM HURT), is also interested in him. Tom claims he has no idea who these men are or what they're talking about and is glad when Sheriff Sam Carney (PETER MACNEILL) steps in to encourage the men to move on.
They do, but it's not long before they're back again with the same claims. With Edi wondering what's going on and Jack following in his father's footsteps in dealing with Bobby, Tom must decide how to deal with this situation that threatens to upend his life in ways he wasn't expecting.
