When Sweety Barrett (Brendan Gleeson) loses his job at a travelling circus he arrives in the port of Dockery, looking for work.

During the days Sweety strikes up a friendship with a six-year-old boy called Conor (newcomer Dylan Murphy), but at night he is unwittingly used by Bone and his gang to do their dirty work. When Conor's father Leo (Andy Serkis) is released from prison and resumes a vendetta with Bone, Sweety Barrett becomes an innocent party caught up in a dangerous and unexpected spiral of events. Just when it seems that Bone is getting away with murder Sweety exacts a spectacular revenge which transforms him into a redeeming hero for the whole town.
