An ancient artifact with powerful secrets, a rogue government agency and a Nazi nuclear weapons factory cause the lives of two women from different times to spin out of control. World War II ended in 1945, but a bizarre incident on an American bomber on a forgotten raid over Germany now threatens the security of the United States. In late July, 1947, Brittany Beardsley had reservations on a flight to Las Vegas where she was to be married the next day. Her flight crashed on takeoff killing all on board in the fiery accident. That she had missed the plane while her fiancé made it were not accidents. In the present time, school teacher Kate Darron's bad day gets much worse when a strange woman wearing clothes from another era knocks on her apartment door. Kate is troubled that the woman seems to know every detail of her life. "Who are you?" Kate asks. "Think of me as the fairy godmother of death," the woman replies. "You shall be dead in less than half an hour." These unrelated incidents bring Kate and Brittany together as they are forced to undertake a terrifying mission across continents and time, one on which survival is not an option.
