Gritty drama set in modern-day Glasgow. Jimmy Kerrigan (former EastEnders actor Alex Ferns) returns to his family home on a tough estate after being detained at Her Majesty's pleasure for nine years on gun-running charges. He finds that both the city and the people he knew have changed irrevocably - his mother is dying, and his brother has acquired a heroin habit. The film charts Jimmy's struggle - at times misguided - to come to terms with his new environment, straighten himself out his lifestyle and help those around him as best he can.
