The story concerns Laura, who has returned with her husband Carlos and adopted child Simon to the large manor where she was raised in an orphanage as a child. Laura is determined to fix up the abandoned house and open it as a refuge for ill children. But from the moment she returns, the past begins to haunt her. It isn't long before she begins to see the children who she used to play with as a seven-year-old. And when Simon goes missing one afternoon, she's convinced that they have taken him hostage. What follows is a murky descent into Laura's mind, where she doesn't know what is real and what is a figment of her tortured imagination.
