Serena is a hardworking professional who travels too much and always comes home with a smile. At least that's what she is to her husband and sons. In truth, she works for a secret spy agency, using seduction to get close to powerful men and take what they were never meant to give up. She keeps her two lives apart with practiced ease, switching between the warm voice on the phone with her family and the calm, precise woman who gets the job done. But the longer she lives both lives, the harder it becomes to tell which one is the mask.
