The main protagonist in Trainspotting, Mark Renton is the Scottish anti-hero who struggles with drug addiction in memorable scenes beginning with a scene in which he fishes a suppository from a blocked toilet to feed his habit. Later he overdoses on heroin and is subsequently held captive by his parents in an intervention where he experiences withdrawal hallucinations. Despite this, throughout the movie Renton remains the most sympathetic character as we occasionally hear his voiceover in the first person. Escaping to London Renton's old life catches up to him as friends get back in touch. The movie closes with Renton departing after stealing the proceeds of a drug deal from his associates.
