London to Brighton (2006) on Netflix

In London, the pimp Derek assigns the prostitute Kelly that works for him to find a young girl on the streets to escort the powerful mobster Duncan Allen. Kelly finds the twelve year-old runaway Joanne in the train station and Derek proposes one hundred pounds for the service and the girl accepts. Kelly befriends Joanne and takes her to Duncan's mansion. When Joanne cries in the bedroom where she is with Duncan, Kelly runs and defends the girl. At 3:07 AM, the bruised Kelly and the tearful Joanne lock themselves in a public toilet. Kelly asks Joanne to stay there because she will raise some money for them to travel to Brighton. Meanwhile, Duncan's son Stuart Allen calls Derek and asks him to meet him in a night-club. When Derek arrives, Stuart tells that his father is dead and he wants the responsible; further, he cuts his knee sinew to prove that he is not kidding. Derek calls his associate Chum and they begin to chase the girls.
