Torchwood - Season 4 Episode 9

Whilst the CIA look in vain for traces of the three families, Esther somehow gets Jack to Scotland, from where they join Gwen and her family in Wales – as, rather surprisingly – does Oswald Danes, claiming he wants to be helpful. He has stolen Jilly Kitzinger's computer, which shows her to be going to Shanghai. After the police have raided Gwen's house and taken her father, she sets out with Oswald and Jack to Shanghai, where Jilly is meeting a woman called Mother. Esther and Rex pursue a lead in South America.
