Hunted

Sam accompanies the Turners on an outing to a go-cart track to celebrate young Edward's birthday. It's the end of the operation as Byzantium intends to assassinate Jack Turner. Things don't quite go as planned. When Stephen subsequently learns what really happened to his wife - and other family secrets - he confronts his father who tells him the truth about why he's out to destroy Polyhedrus. More convinced than ever that Alex is a spy, Jack Turner decides to get rid of her. Sam continues to struggle with the memories of her past. Aiden is convinced that something happened in those past events which will explain why she is a target today. She begins to remember.

Sam breaks into Stokes' house and finds a Top Secret file on her as well as a document relating to the death of her mother Katherine,killed when Sam was a child. Aidan believes that back then Sam saw something which has made her a mark to be killed.Ian tracks Turner to a meeting with Pakistani minister Soomro,who wanted Fatima dead and who tells Turner the dam is to be sold to the Chinese. Turner however tells him that he will expose Polyhedrus's shameful secret unless he gets the bid. Sam learns the secret - Polyhedrus massacred six hundred Pakistani villagers to clear the site for the dam,making it look like an accident and Hill and Goebel were killed as they were about to expose the fact. It seems that Byzantium's client is Stokes,who instructs Keel to have Turner murdered. Natalie believes the file on Sam was given to Stokes by government minister Gillespie and warns her,also giving her a key that will lead to Aidan's real identity. Stephen meanwhile is assuaged by Sam's assurances and anxious to build a case against his father for his involvement in murder. However Turner informs him that Sam is a spy and they must tolerate her until her motive for being in their house is made clear.

Aidan survives the explosion but is accused of being the mole and goes on the run,asking Natalie,in vain,for information on Hour-Glass. Sam wakes in hospital to find that,rather than seek her death,the blank-faced man has put her there to warn her that she is in danger and explains that he had to assume Goebel's identity to get close to Turner. Giving Stephen a cover story Sam discharges herself and confronts Aidan. He tells her that he was blackmailed by Natalie to spy for her - she would otherwise expose his true identity.They meet Ballard and ask for information on Hour-Glass but a sniper kills Ballard. However they learn that Hector Stokes,part of the group building the dam,is a member of Hour-Glass and go to see him . They are shadowed and kill their pursuers but Aidan is recaptured by Byzantium and tells them that Hasan was the traitor.Following the blast Turner gets the money for his bid but Turner is still looking for the woman who saw him kill Cage and Keel lays a trail leading him to suspect Conroy's married lover Trudy. Ryder introduces Ian to Turner as a useful gang member. On television they see Fatima Zahir,a leading Pakistani politician, speak out against the sale of the dam.
