A wild, freeform, Rabelaisian trip through the darkest recesses of Edinburgh low-life, focusing on Mark Renton and friends: Sean Connery wannabe Sick Boy, dimbulb Spud, psycho Begbie, and clean-cut athlete Tommy.
Hilarious but harrowing, the film charts the disintegration of the friendship between Renton, Spud, Sick Boy, Tommy and Begbie as they proceed seemingly towards a psychotic, drug-fuelled self-destruction.
After 20 years abroad, Mark Renton returns to Scotland and reunites with his old friends Sick Boy, Spud and Begbie.
