A jarring, fragmented ride through the dark underbelly of Edinburgh, the festival city. There is not an advocate, a festival performer or a fur coat in sight as, with bitter passion and rancid humour, Welsh lays bare the lives of this ill-starred bunch of addicts, alcoholics and no-hopers. Rents, Sick Boy, Mother Superior, Swanney, Spuds, and Seeker are as unforgettable a clutch of junkies, rude boys, and psychos as readers will ever encounter.

Ten years after the events detailed in "Trainspotting", Simon Williamson, a.k.a. Sick Boy, is back in Edinburgh to direct and produce a porn film along with university student Nikki Fuller-Smith and old friend Mark Benton.
