Through a DNA link the pathologists find that John Dear was a client of unwilling child prostitutes Shannon and the deceased Amy whilst the suitcase victim is also identified. Nikki visits Shannon in hospital and learns about the gang of abductors but the young girl is too scared to name names. Through CCTV DS Masood gets the car registration number of a visitor to Shannon and arrives at a taxi firm where Salman,a somewhat reluctant and kind-hearted gang member, works. Salman helps Hannah and Lauren escape but is killed when his taxi crashes. The three girls are returned home but will not speak about their ordeal and,with Abdul swearing revenge, Nikki must help DS Masood resolve matters. The case closed Harry announces that he is leaving to take up a professorship in New York.
