Now imprisoned, Fran watches her captor live out her dream friendship on CCTV. But when Jamie starts to smell a rat, the plan changes quickly.
Convinced that Kat is up to no good, Fran hires a private investigator to dig up some dirt as she and Jamie prepare for their final hit.
With their partnership increasingly fraught and the blood of a funeral director on their hands, Fran and Jamie are pursued by the man's vengeful son.
After killing a drug lord prematurely, Fran and Jamie hire a bit-part actor to impersonate him - but the thespian has too much gusto for his own good.
Having stumbled into a career in contract killing, misfits Fran and Jamie are not your typical killers for hire. Working out of their scruffy van, each episode follows the hapless duo as they try to carry out their latest hit, inevitably derailed by incompetence, bickering, and inane antics. As each hit goes south, our (anti)heroes are thrown into one bizarre misadventure after another, each full of oddball characters and unexpected dilemmas.
