Game On

Martin meets a nurse named Clare, who agrees to go out with him. She tells him that she wants to lose her virginity. After a few mishaps, Martin finally makes love to her. Meanwhile, Matthew decides to stay in bed and Mandy resolves to become celibate.

Martin can't stop talking about his newfound sex life. Matthew confesses to Mandy that he's terrified of going out of the house. She arranges for him to meet her friend Jason, who's a psychologist. Jason is gay and, after talking to Matthew, he tells Mandy that he's fallen in love. Mandy starts an Italian evening class and her tutor, Marco, shows an interest in her. When she tells him that she's celibate, he misunderstands and thinks she's trying to say that she's a virgin. Martin and Mandy discover Matthew in bed with Jason. Matthew doesn't know that Jason is gay.

Jason manages to persuade Matthew to go out to the park and, later, to a gym. Matthew shows Marco a video of Mandy having sex, so Marco realises that she isn't a virgin and decides he's no longer interested in her. Meanwhile, Martin has become very insecure about his relationship with Clare. A combination of paranoia, jealousy and drink leads him to make a complete fool of himself. Matthew finally manages to go out on his own, on a trip to a local shop. Unfortunately, the shop is raided by a masked gunman, so Matthew decides that he'll never go out again!

Mandy is visited by Stoat, an old boyfriend. When the flatmates discover that he's escaped from prison, Stoat ties up Matthew, Martin, Jason and Clare. He takes Mandy into her bedroom and they end up having sex. Mandy ties Stoat to the bed and gets his gun, then releases her friends. Clare tells Matthew that Jason is gay. Jason leaves and Clare dumps Martin.

Martin is very depressed about the end of his relationship with Clare. Matthew is spending his time writing a 'secret' journal. Mandy has a close encounter with Brian Kennedy, a lecturer from her old university. Martin and Mandy find out what Matthew has been writing in his journal.

Martin realises that Clare left him because he's boring. He starts a voluntary job, working for a telephone helpline for distressed people. He gives his home phone number to Tesni, one of the helpline's clients. She rings the flat while Matthew is at home alone and, thinking that Matthew is Martin, she threatens to commit suicide unless he visits her home. Matthew goes round to see her but, when he gets there, he collapses and has to be rushed to hospital. Martin arrives at the hospital, looking for Clare. Mandy also turns up, with her latest boyfriend. Matthew meets a red-haired student named Susie and falls in love with her.
