Eric used to be an agent working for the CIA, with vigorous skills and rich experience. Now, although he has already left the organization, he has never given up on special training for his daughter, because he understands that for Hannah, everything he has learned now will be useful in the future. Mary (Mireille Enos) is Eric's former contact, and Eric's sudden disappearance has brought great trouble to her life and work. Suddenly one day, Mary received a mysterious message that reminded her of Eric's whereabouts.
