When real estate agent Carmen Colson (Lane) catches a glimpse of a hit man named the Blackbird (Rourke) as he carries out a job, a subsequent request for her to testify against the aging gun for hire soon lands both Carmen and her husband, Wayne (Jane), in the Witness Protection Program. Blackbird isn't a man who likes to leave loose ends when it comes to his work, though, and now as the seasoned assassin and his psychotic partner (Gordon-Levitt) attempt to catch the couple in their crosshairs, Carmen and Wayne are going to need much more than a few federal agents to make it out of increasingly deadly situation alive.
