Jamie and his best friend Mike are looking forward to a carefree summer as their exams are over and they're on mission to crash the sixth form party and get laid. 18-year-old Laura is convinced by her friend to attend the same party. Laura ends up in Jamie’s nervous but willing arms. A few weeks later Laura realises that she’s pregnant. When she informs Jamie she is shocked to find out that the's only 16.

Laura is still finding it hard to come to terms with the fact that she is going to have a baby. She wont talk to Jamie, but encouraged by her best friend Danielle, she decides to book an appointment to find out what her options are before she makes any rash decisions. Jamie, upset that Laura's isn't taking him seriously, decides to ask her to marry him.

Laura is still no nearer to coming to a decision on whether to have the baby and leaves to go to university. After Jamie learns that she has gone without telling him, he is not happy and decides to follow her to Edinburgh. Beth ends up realising that if she wants any chance of getting together with Jamie she's going to have to make her move straight away.

Jamie's 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 foreseen how badly it would 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 is 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.
