At the heart of the drama is Sam played by Melissa George (The Slap, In Treatment), a highly skilled operative for an elite private intelligence firm who survives an attempt on her life that may have been orchestrated by members of her own team. Once she returns to the firm, she performs her secretive duties without knowing who to trust and who wants her dead.
Adam Rayner (Hawthorne, Mistresses) plays Sam’s colleague at the firm and love interest. The dedicated and complex members of the firm operate in the shadows, must often confront life and death situations on secret missions and are sometimes unaware of who or what they are fighting for.
