Jamie is turning 18 and Mike has taken over organising the party. His main mission is to source some high-quality, mind-altering substances. Mike decides to go organic and get hold of some mushrooms. Beth comes on the hunt and steers him towards a harmless non-psychedelic type. Meanwhile, Keith has been forced to take a new-age influenced 'back to work' course. He goes on an accelerated journey of self-discovery. He's getting fitter, and closer to the eternal truths of the universe but he's no closer to getting a job.

When Laura learns that Jamie has a date, she goes out of her way to get one herself. She wants to show him that if he's over her, she can move on too. She arranges an internet date with Marcus, a proper, grown-up man with a flat and a job. But, on Danielle's advice, she chooses not to tell him about being a mother for the time being. Mike is on a body-transforming course combining high-strength Russian muscle steroids with a kettlebell workout. But the side effects are taking their toll on his waistline and his emotional state. Keith is approached by a model agent offering work for Emily. He and Sandra enter the world of baby modelling, but soon find out it's more competitive, catty and aggressive than they imagined.
