Finn and Ronan's party in an abandoned mill is the talk of the school, but the boys' bragging ends up alienating the only two girls they want to show up: Vicki MacDonald and Sambuca Kelly. Jonah considers leaving school if it means he can be with Cesca earlier, not realising that Cesca has discovered she is pregnant. Later, at the party, events escalate out of control, and it is up to Tom to save the day.
