The Secret on AllMovie

Inspired by the Japanese drama Himitsu (which was in turn based on the novel by author Keigo Higashino), director Vincent Perez's supernatural drama tells the tale of a mother who discovers some shocking secrets about her teenage daughter after being killed in a tragic car accident and seeing her soul inexplicably transplanted into the body of the troubled young girl. Benjamin (David Duchovny) and Hannah (Lili Taylor) are happily married soul mates, yet neither parent realizes that their adolescent daughter Sam (Olivia Thirlby) is leading a desperate double life. One day, seemingly out of the blue, Benjamin and Sam find their lives changed forever when Hannah is killed in a violent car accident. But at the moment of death, Hannah's soul is somehow propelled into Sam's body, giving the mother a chance to know her beautiful daughter more intimately than she ever did in life. Unfortunately the things that Hannah discovers about Sam are deeply disturbing; Sam has been leading a secret life - a life that neither Hannah nor Benjamin ever knew anything about. Meanwhile, back at home, Hannah and her grieving husband receive one last chance to rekindle their romance and say their last goodbyes.
