A mysterious assassin tells Sam that he is trying to protect her from Hourglass, a conspiracy orchestrated by five multinational corporations. Sam's investigation of the conspirators takes her to a country estate where she had been years before - it was where she was taken as a child after her mother was murdered and she was kidnapped.

Jack Turner demands he be awarded the dam, revealing he has evidence implicating Byzantium's client in a terrible crime. With the operation nearly over, Aidan presses Sam to revisit childhood memories of her mother's murder and her own kidnapping - to understand the reasons why the Hourglass conspirators have targeted her for death.
