It's the last weekend of the summer holidays and Jonny is ready for a big night out with his two best friends, Neve and Louis. Jonny and Neve, partners in crime, are over-excited and go hard on the rides (and the drugs), while sober Louis nervously worries about how their night will turn out. They try to befriend Regan and Zia but end up embarrassing themselves and being brushed off. On the walk home, as they approach Jonny's family pub they see his dad being stretchered into an ambulance.

Mei's recently moved back to Welwyn from Canada after her parents' marriage broke down. She knows there's something her mum, Jing, isn't telling her about her dad but when she finds out, Mei
takes teenage rebellion to the next level.

Louis wants to be treated like a grown up by his friends and his dad, Gareth. With his 17th birthday approaching, he is also desperate to lose his virginity before the big day. Neve persuades him to ask Zia out, and Zia says yes, leaving Louis simultaneously thrilled and terrified. Jonny gives Louis some unconventional advice about sex, as does Gareth. But when the moment comes with Zia, will the pressure get too much or will he manage to lose his virginity before turning 17?

When Neve's strict parents go on holiday to Nigeria, Neve is delighted at the prospect of being home alone. Until her sister Timmi shows up, sent by their parents to babysit her. Neve is sick of living in Timmi's shadow - Timmi is hugely successful and their parents have her on a pedestal. Even Neve's teacher hopes Neve will be the face of the college open day - just like Timmi was. So Neve is delighted to discover Timmi might not be as perfect as everyone thinks.

Regan has to be very organised as her gran's carer. But her gran now needs a professional, which is how the chaotic Jaz arrives in their lives. Regan is unsure of Jaz and resents how much her gran is enjoying her company. The gang have to attend a careers fair. Neve signs up to a volunteering programme and meets Marcus, who patronises her, but who she can't help liking. Zia impresses PR-hotshot Sasha and bags herself a trial internship.

After hitting rock bottom, Jonny finds himself in therapy and seems to be on track to getting better. However he's frustrated his family still can't talk honestly about their emotions.
