Still scheming, still scamming - it's ten years later and the boys from Trainspotting are still trying to fight for the first-class seats as the locomotive careers at high speed towards the buffers. Simon "Sick Boy" Williamson is back in his native Edinburgh after a spell in London. Having failed spectacularly as a hustler, pimp, husband, father and businessman, he taps into an opportunity, which to him represents one last throw of the dice. For this scam to work, Sick Boy needs bedfellows. A desirable one may be the lovely Nicola Fuller-Smith, a young student with enough ambition, ego and troubles to rival his own. However, to realize his dream of directing and producing a pornographic movie, Sick Boy teams up with old pal and fellow exile Mark Renton and a motley crew that includes the city's favourite ex-aerated-water-salesman, "Juice" Terry Lawson.
