After Fran has a secret meeting with a private investigator Jamal to dig up dirt on Kat, she and Jamie shop for their last hit together. Fran seems surprisingly upbeat about the end of their professional partnership, clearly convinced that she will be able to expose Kat to Jamie. But when Jamal discovers nothing, the guilt kicks in and Fran and Jamie get emotional as they take out their final hit - gobby spa owner and human trafficker Siobhan.
Having stumbled into a career in contract killing, misfits Fran and Jamie are not your typical huggers 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.
