Trainspotting is the tale of Scottish heroin junkies and their lives in Edinburgh. The motley crew of addicts (Mark Renton, Spud, Alison), an unhinged man whose drug is hurting people (Begbie) and the clean ones, (Tommy, Gail, Lizzy). Mark makes a decision to quit heroin and is joined by his friends (one of which just comes off it to prove to Mark he can do it easier than he can). While off the skag, the friends go through numerous unfavourable events, prompting them to resume their addiction, but a tragic turn of events makes Mark resolve to leave his old life behind and go to work in London. He soon finds out that he can't always leave his past behind that easily.
