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.
Moz tries to hide his dope dealing from the born again Christian builders working in his flat, and lack of sleep is making Nicki hallucinate. Judith the 'reformed' necrophiliac is seen dragging heavy sacks up the stairs into her flat.
The Police Constable has fallen in love with China, Nicki thinks she's losing her mind and Brian has turned into a Goth. Meanwhile, Moz is forced to perform an exorcism on Jenny the child minder.
Moz is desperate to disuade Cartoon Head and Psycho Paul from shooting a porn film in his bathroom. His mother Sheila joins a dodgy pyramid selling scheme and Nicki and Brian are involved in a car crash.
Moz receives an unwelcome visit from gang leader, Stemroach. Meanwhile, the discovery of a wasp nest in the loft has disastrous consequences for the born again Christian builders.
Moz's attempts to enjoy a nice, warm bath are continually thwarted, initally by a steady stream of visitors requiring weed, advice and a shoulder to cry on, then by a bizarre murder.
With Nicki out celebrating her hen night, Moz reluctantly agrees to help the Police Constable to set-up Stemroach. Meanwhile Cartoon Head and Psycho Paul have an evil plan all their own.
Moz is trying his best to enjoy his stag night. However, Judith has had a party mask super-glued to her face, three crabs have escaped in the flat and Jesus has just appeared in the loft.
It's the morning of Moz's wedding and he's woken up next to another woman. Now all he has to do is get rid of her, overcome his nerves, deflect the advances of a very demanding Judith and save Brian from a psychopathic Christian.
