The game is almost up for Paddy's conniving mother. She's had her son in a spin since she revealed that she only had a short time to live. Already she's caused Mandy and Paddy to split again and even suggested as a dying wish that Paddy might marry his childhood sweetheart Jane - just to make her happy. Paddy tells Mandy his mother's wish and while he has no intentions of carrying it through, Mandy decides it's about time she had a little word with Mrs Kirk herself. But after finding her home empty the trail leads to a health centre where Mrs Kirk is caught - working out on a fitness machine! Rachel and Graham get the hard word from headmistress Miss Strickland for wasting her time. Graham reluctantly admits he gave her the wrong impression about Rachel wanting to leave. Later Graham interrupts an illicit meeting by the school gates and as people rush away, he finds a packet of cannabis resin on the floor.
