Ben Kinnear (Molloy) and Mike Paddock (Franklin) are police officers working for the Zero Tolerance Unit, a special division of Victoria Police. When they accidentally shoot the corpse of a judge several times each, they are reprimanded but investigate his death, leading to several other accidents, for which they are relegated to uniform duty. Through Julie Bale (Lucy), a former police officer and Kinnear's ex, they uncover a conspiracy involving the Zero Tolerance Unit and extending all the way to the Premier of Victoria (Micallef).
