one last throw of the dice. However, to realise his ambitions within the Adult industries, Sick Boy must team up with old pal and fellow exile Mark Renton. Still scheming, still scamming, Sick Boy and Renton soon find out that they have unresolved issues to address concerning the unhinged Frank Begbie, the troubled, drug-addled Spud, but, most of all, with each other. T2 Trainspotting was previously published as Porno.
