Set in a colorful yet gritty 1970s Boston, Free Fire opens with Justine (Oscar® winner Brie Larson), a mysterious American businesswoman, and her wise-cracking associate Ord (Armie Hammer) arranging a black-market weapons deal in a deserted warehouse between IRA arms buyer Chris (Cillian Murphy) and shifty South African gun runner Vernon (Sharlto Copley). What starts as a polite if uneasy exchange soon goes south when tensions escalate and shots are fired, quickly leading to a full-on Battle Royale where it’s every man (and woman) for themselves.
