Both Fran and Jamie aren't your usual assassins for hire, having accidentally stumbled into a profession in contract murdering. Episodes follow an incompetent, bickering team who try to carry out their next smash, only to be disrupted by their inane antics, squabbles, and mishaps. Every time a hit fails, our (anti)heroes are thrust into a new, unusual misadventure, complete with strange characters and unforeseen problems.
