Moz's day gets off to a bad start when he is woken up by the phone. It gets worse when his girlfriend Nicki complains about the state of their flat and when she discovers a rat in the flat, she punches Moz on the nose and decides to move out.

Moz tries to get the ratcatcher to come round and get rid of the rats so that Nicki will come back but Cartoon Head has his own ideas about how to get rid of them.

Colin calls round, full of grisly tales about a dismembered body found opposite his bedsit. Nicki finds an alternative use for the rat poison and Cartoon Head leaves something in Moz's bin.

Moz finds something unpleasant in the pocket of his jacket and Colin pays a visit to try and sell Moz some stolen goods and pockets Nicki's secret polaroids for good measure.

Nicki realises that her polaroids are missing and is worried that Moz might have seen them. Although he wants to reconcile his relationship with Nicky, he is preoccupied by trying to sell the new gear that the PC has supplied.

It's Moz's 30th birthday and Nicki's organised a surprise party to celebrate but everyone's having fun apart from Moz. To make matters worse, his brother Troy, sees something he shouldn't from behind the shower curtain.
