Avsnitt 5

A young Russian girl leads Dale Smith out of a nightclub, where he is promptly attacked by three men. Despite Smith's protests, Supt. Chandler assigns DI Cullen to investigate the assault. They track down the Russian woman, Natasha Ivanova, through a language school which seems to be recruiting students to work as prostitutes. Natasha is desperate as her visa is about to expire, and her sister has disappeared . Her sister is found murdered, and Smith realises the men responsible for her death and his assault are linked to a man from his old army unit (episode: Blurred Around the Edges).
