A mercenary takes on the job of tracking down a target on a plane but must protect that target when they're surrounded by people trying to kill both of them.

'Fight or Flight' is an action-packed thrill ride with humor and violence, often compared to 'John Wick' and 'Bullet Train'. Josh Hartnett's charismatic performance is widely praised. The relentless action sequences and stylized combat are highlights, though some find the plot underdeveloped and lack originality. Humor receives mixed reactions, and the abrupt ending, hinting at a sequel, is criticized. Despite these issues, it is generally considered a fun, though not entirely serious, watch.
