Baz is one of Britain's new breed of police, a cycle cop. Although he appears to be a figure of fun, a freak accident turns him into a psychopath...As riots break out in London, a head injury changes Baz from an everyday police officer into a mad vigilante, offering no-hope criminals a stark choice, arrest or death. Baz sees this campaign as 'lawful killing'. Criminals too stunned, confused, or drunk to argue are politely asked, "May I kill you?" and merrily dispatched on their final journey. All these exchanges are recorded on Baz' helmet-cam and posted anonymously on social networks. Using the alter ego '@N4cethelaw' Baz acquires an increasing number of fans with each killing, dispensing justice to scumbags, cleaning up society like some bizarre and deadly 'Robin Hood', ridding society of its' ills.But, in a sudden reversal, Baz is captured by an enraged relative of one of his presumed "kills" and faces slaughter or even worse... exposure.
