Hitman Charlie Swift (Pierce Brosnan), known as "Fast Charlie," is the consummate fixer with a problem: the target he's just whacked is missing his head. The only way for him to get paid is to prove it's the intended target to the man who paid for the hit - New Orleans' most ruthless mobster, Beggar Mercado (Gbenga Akinnagbe). Charlie enlists Marcie Kramer (Morena Baccarin), the victim's ex-wife and a woman with the backbone and skillset Charlie desperately needs. Dragging Marcie back into a past she was determined to escape sends the two of them on a wild and unpredictable odyssey that's at once hilarious and action-packed, and ultimately heartfelt. Throughout their journey, Charlie and Marcie fight to protect the legacy of Charlie's best friend and mentor, Stan Mullen (James Caan), while trying to bring down Beggar and his entire operation.
