The first collaboration between director Ken Loach and screenwriter Paul Laverty - a relationship which now extends to fifteen feature films and shorts, including My Name Is Joe and I, Daniel Blake - Carla's Song tells the story of George (Robert Carlyle, Trainspotting), a Glaswegian bus driver, and Carla (Oyanka Cabezas), a Nicaraguan refugee.
Set in 1987, the film follows the pair as they meet, fall in love, and travel to Nicaragua in search of Carla's former lover, a possible victim of the civil war.
