Moz has been dealing drugs for over twenty years from his small bedsit in Manchester which he shares with his girlfriend, Nicki. But despite his chosen profession, Moz is a man of principles - he deals only in the best quality marijuana and nothing else. He is providing a crucial service to the local community, which pretty much extends as far as his closest friends: Kuldip, an Asian DJ and police constable who is also Moz's chief cannabis supplier; Jane, the childminder from hell; Brian, a camp scally who seems to have a new boyfriend every week and a man who always wears a cartoon mask, simply known as 'Cartoon Head'.
