Moz is a small-time (hash only) drug dealer. He rarely sets foot outside the confines of his squalid Manchester flat he shares with his long-suffering girlfriend Nicki. He's a lazy slob basically - as Nicki comments, "Jesus, Moz. I've seen coma victims with more 'get-up-and-go'". The series provides a window onto his life, and the bizarre sequence of people who come round to score from him. His dealer is a dodgy copper, his girlfriend is fed up with him, and he has visits from a silent man who wears a cartoon mask.
