Jamie has just finished his exams and his carefree summer is off to a great start. He has crashed a sixth-form party and hooked up with an older woman, 18-year-old Laura who is also looking for some uncomplicated fun. But thanks to a combination of post-exam euphoria, too many drinks and an available bedroom, they soon find they have one very serious complication on their hands - Laura is pregnant. So even though they barely know each other, they now have one big thing in common - and it's getting bigger.

Laura is in shock, having discovered that Jamie is only 16 years old, and refuses to speak to him. Jamie feels that Laura is not taking him seriously and decides the only way to get her attention is to propose. Janet and Alan are in counselling, trying to repair their marriage, but their guidance counsellor Jeremy doesn't really seem up to the job.

Laura is no closer to making a decision on whether to have the baby, but heads off to university anyway. When Jamie finds out she has gone without telling him, he is furious and decides to follow her to Edinburgh... but he's definitely not stalking her. Meanwhile, Beth realises if she wants any chance of getting together with Jamie she's going to have to make her move now.

Jamie and Laura's parents meet for lunch to discuss the future of their families. Laura and Jamie are rightly apprehensive about a family summit, but even they couldn't have forseen how badly this was going to go. Meanwhile, whilst making up the numbers on Beth's double date, Mike faces a sexual dilemma when he's offered a threesome with stunning Carrie-Ann and her handsome gay friend, Aaron.

Laura is settling in well at Jamie's place - a bit too well. Keith is sick of her being there, Jamie's tired of sleeping on the sofa, and Mike and Beth have had enough of not being able to see their mate. Something's got to give but the eventual confrontation kicks off a much bigger crisis.

Laura is very pregnant, very bored and cannot stop thinking about Jamie. So she asks him to take her on a casual shopping trip - casual that is until Laura goes into labour. Meanwhile, Mike is faking a charity run to raise money to pay for a prostitute. Keith takes Sandra to the Lakes to break the bad news about losing his job. Janet and Alan, however, are getting along extremely well, in fact they are downright frisky.
