A child... only in her mother's mind.
Annie (Rita Wilson, That Thing You Do, Sleepless in Seattle) is the perfect wife and loving mother of two children, who believes she has a third child named Maggie... only Maggie does not exist! Her husband, Tom (Victor Garber, TV's "Alias," Legally Blonde), hires Gillian (Tushka Bergen, Barcelona) to become their nanny. The whole family has played along with Annie's delusion for years, hoping it would pass. Gillian is asked to do the same. Months later, Gillian decides to try and help Annie and does some research on her own. Unintentionally, she alerts authorities who launch an investigation. Will she be responsible for having Annie institutionalized, and taken from her family... a family that Gillian has grown to love?
