Desperate to uncover the truth, Grace turns to Maddy's journal for clues, piecing together fragments of the past while questioning everything she thought she knew about their relationship. As memories resurface and disturbing secrets emerge, Grace must confront the possibility that the truth is far more terrifying than she imagined.
