The Disappearance of Christina

On a sailing trip off Los Angeles, Christina vanishes from the deck while Joe and their friends Mike and Lily are aboard. A search is launched, but no trace of Christina is found and the mystery begins. The disappearance sets off a tense scramble among the group as investigators start to pry into what happened.

The next day, Detective Davis informs Joe that Christina had signed divorce papers two days before she disappeared, contradicting Joe’s belief that their marriage was fine. Joe wrestles with the shock and questions the motive behind Christina’s actions. The revelation casts doubt on Christina’s plans and signals deeper secrets.

Joe experiences a vivid dream where Christina tries to drown him, blurring the line between fear and reality. He wakes unsettled, convinced the dream carries a warning. The dream deepens his sense that something dangerous is unfolding around him.

Several days later, Mike and Lily visit Joe to check on him and bring food, and he tells them Christina had filed for divorce. Mike suggests Christina may have committed suicide or fallen overboard, while Lily grows more wary. The conversation adds to the mounting tension and mistrust.

Joe later receives a phone call from a voice that sounds like Christina, saying, 'I’m sorry I didn’t say goodbye.' The call intensifies his belief that Christina is alive and reaching out from beyond. The eerie message unsettles him and those around him.

That evening, a fundraiser honoring Christina unfolds and Joe tells Mike that Christina had called him. Mike and Lily grow increasingly concerned about Joe’s mental state as he clings to the possibility that Christina is alive. The tribute turns into a charged, uneasy event.

That night, Joe searches Christina’s date book and has another dream about her. He discovers the date book is missing, and he feels as if someone has been in his house. The eerie loss deepens his fear that Christina may be closer than anyone admits.

Joe and Lily go to Christina’s sister Madeleine at a psychiatric hospital, but Madeleine is incoherent and unhelpful, claiming Christina visited the day before and then flew away. Joe spots Christina’s bracelet on Madeleine’s wrist and tries to wrest it away, triggering an alarming outburst. Detective Davis later confronts Joe about the alleged assault.

Late one night, Joe finds Christina’s red dress in the dryer and hides it, but a maid takes it to the police, leading to Joe’s arrest for murder. He is released due to a lack of hard evidence, and the mystery tightens around what really happened. Investigators press on for real proof of Christina’s fate.

Joe and Lily go to the coroner’s office to identify a body, but it is not Christina. Lily privately tells Detective Davis she believes Christina is still alive, which reframes the entire investigation. Suspicion shifts toward hidden finances and possible deceit within the relationships.

Investigators uncover large unexplained financial discrepancies on a major construction project, and Christina’s date book is found along with a gun in Mike’s office. Joe and Lily trace a condo by the marina where Mike and a woman resembling Christina had a February deal. They also uncover a secret crawl space in the marina boat cabin that could have concealed someone.

Lily reveals she has been gaslighting Joe to make him doubt Christina’s fate, and confesses to killing Mike to cover up the affair and the fraud. Joe survives the confrontation, and Detective Davis arrives to reveal the red dress was brand-new and never worn by Christina. In the final moment, a figure resembling Christina is seen at the water, implying she may still be alive.
