In the British seaside town of Brighton, two major gangs, Cates and Carlinori, are entrenched here, wrestling with each other and growing stronger while the other grows weaker. One night, Cates was killed by his rival in the street. Pinky (Sam Riley), who regarded the boss as his own father, witnessed the whole process of the murder, so he wanted to hunt down one of the participants, Fred (Sean Harris). Although Fred died, he left a lot of trouble. In order to avoid being followed, he once took a photo with Rose (Andrea Riseborough), a waitress in a restaurant. In order to destroy the evidence, Pinky began to approach this simple girl, and Rose gradually fell in love with the handsome and cold Pinky. At the same time, Cates's death also unbalanced the gang forces in Brighton. On the one hand, Carlinori expanded rapidly, and on the other hand, there was a power struggle within the gang. Pinky was deeply trapped in it and couldn't extricate himself... This film is adapted from Graham Greene's novel.
