Frank Carden (Morgan Freeman), one of the world's greatest assassins, is handed a lucrative contract to kill a highly secretive billionaire. But in a twist of fate, Carden is involved in a car accident during the job, and when his gun is found after he is admitted to a hospital, federal marshals arrest him. Meanwhile, ex-cop Ray Keene (John Cusack) is hiking with his son, Chris (Jamie Anderson), when Carden's cohorts try to spring him from custody, and soon the pair is caught in the crossfire.
