We follow the hits and (more often than not) the misses of two hapless, dead-broke contract killers who frankly, are more of a danger to themselves than to anyone else. Each episode sees Fran (Sue Perkins) and Jamie (Mel Giedroyc) try to track down and kill a different target. But every hit turns into a shambles of mistaken identities, mistimed entrances and misfiring weapons. ..ccc
