After witnessing the brutal murder of his parents as a young boy, Chance Templeton (Rick Yune) is taken in by a ruthless killer (Keith David) and raised to follow in his footsteps. An assassin's trade is solitary by nature, but Chance shares a tight bond with his adopted brother, Miles (Bokeem Woodbine), who's elected a more honorable path working as a bodyguard for a sultry pop star (Dania Ramirez).
When Chance is contracted to gun down his brother's client, he realizes there is finally a line he cannot cross. Uniting with his brother to stave off an expected hit, Chance finds himself targeted by the elite members of his own profession as he struggles to protect a woman who stubbornly rejects his services.
