Tiger Bay (1998)

Rough-and-tumble street urchin Gillie (Hayley Mills) witnesses the brutal killing of a young woman at the hands of visiting Polish sailor Korchinsky (Horst Buchholz). Instead of reporting the crime to the authorities, Gillie merely pockets a prize for herself -- Korchinsky's shiny black revolver -- and flees the scene. When Welsh Detective Graham (John Mills) discovers that Gillie has the murder weapon, the fiery young girl weaves a web of lies to throw him off course.
