Episode list

Raban discovers that two Iranian cousins have been murdered. Some investigation links the killings to a policy group called Defence Concern, headed by Daniel Cosgrave. Raban believes that Defence Concern had something to do with the killings, and recruits Cosgrave's policy advisor Alice Ross to help him uncover the truth. That night, Raban is approached in a cafe by Blake, a member of the death squad Pugnus Dei ("God's Fist"). Blake tells Raban to keep out of their business. Raban is amused and remains so as Blake makes a telephone call ordering Carolyn's death. As Blake leaves, Raban's smile fades and he runs to Carolyn's house.

Raban finds Carolyn lying dead in her front doorway. The police arrive and suspect Raban of killing her. As his daughter is taken away to stay with her aunt, Raban flees the scene. He arranges to meet with Kerrigan to tell him what he has discovered. Ross accesses a confidential file that she downloaded from Cosgrave's computer and discovers the name of one of the Iranian cousins, proving Raban's claim of Defence Concern's role in the killings. She arranges a meeting with him and Raban meets with Kerrigan. Raban is forced to flee again when Kerrigan double-crosses him and brings the death squad to kill him. He arrives at the meeting place and finds Ross submerged in a bathtub.

Raban revives Ross and they discuss the implications of Defence Concern's actions. Raban believes that Pugnus Dei is being funded by the Validus Group, an American private equity group and a significant global arms dealer. It is headed by Donald Hagan, a former United States Secretary of Defense. In the denouement, Raban holds Hagan at gunpoint until he realizes Hagan's death is what the death squad wanted all along. After Raban leaves, Blake shoots Hagan, hoping the death of such a high-ranking official will start a new War on Terror. Raban, still being tracked by the police, contacts his daughter and asks her to upload the contents of a CD to the Internet. Pugnus Dei's plot is revealed to the public and Raban is reunited with his daughter.
