First there was an opportunity......then there was a betrayal. After 20 years abroad, Mark Renton returns to Scotland, the only place he can ever call home, and reunites with his old friends Sick Boy, Spud and Begbie. Other old friends are waiting too: sorrow, loss, joy, vengeance, hatred, friendship, love, longing, fear, regret, diamorphine, self-destruction and mortal danger, they are all lined up to welcome him, ready to join the dance.
