There's a party at one of Thomas' club nights and all the gang are there; Cook is still up to no good, Freddie is learning increasingly more about love and the girls are busy dancing. An accident during the evening, however, leaves Thomas feeling guilty and alienated from the rest of the group. Will their friendship survive?

After failing to reign in his jealousy of Freddie and Effy's reunion and hospitalising the kid he beat up in a room full of witnesses, Cook finds himself in prison. When released on bail, he is forced to live with his mother due to the terms of his electronic tag. His mum is a successful artist who owns a mansion, but it's no holiday for Cook; he and his mum clash again and again. With few people to talk to, Cook is helped by an unlikely ally and begins to question his actions.
