From laughter to slaughter only takes the letter of the law. Bicycling bobby Baz Vartis (Kevin Bishop) sees guilty people. He's the London policeman with a murderous difference, a vigilante cop who simply says "Stop!". For when Baz is hit on the head in a scuffle with looters during the London riots, he turns into a psychopath on the cycle path. With a helmet-cam for company, he pedals forth in search of criminal scumbags who, in their last moments, filmed and posted on social media, agree to die for their sins. Many believe he's a hoaxer. Others think he's a hero. Whatever, his fame as a 'dread' judge with a death wish grows. Until Baz meets his nemesis - and retribution finally comes with hilarious and devastating consequences.
