After a violent incident in their shared past forces the lives of brothers Frank and Henry Lincoln to diverge, each carries on in the name of his own interpretation of justice, until, after 35 years, the paths of estranged brothers Frank and Henry Lincoln finally cross again. Frank, who has spent his life becoming a distinguished member of the San Francisco police force, is approaching retirement, investigating one last case with his young replacement. Meanwhile, Henry Lincoln, a vigilante whose vision of justice is far darker than the law allows, has finally returned to his native San Francisco, his sights set on recruiting Isaac Lordman, a former policeman, to follow in his footsteps. Sparks fly as the two brothers and their differing visions of justice collide - and the fate of the city may hang in the balance.
