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.
