Cassandra

Cassandra experiences recurring nightmares of a woman committing suicide at the command of a demonic little boy. Each dream ends with the house catching fire, leaving her shaken and convinced something real is happening. The dreams set the tone for a past that feels connected to her family.

As memories remain suppressed, Cassandra grows convinced that the boy and the woman are linked to a hidden past, possibly a twin brother. She suspects her family is hiding crucial truths about their history. The idea of repressed memories becomes a driving force behind her investigation.

At the family beach house, Cassandra discovers a photo of the woman from her dreams identified as Jill, the father's sister who killed herself. The discovery makes her question everything and suspect her parents are lying about her origins. The photo links the nightmares to a real, hidden family history.

Cassandra questions her photographer father at the family beach house and learns he has been cheating with one of his models. The revelation adds to the sense of a fractured, secret-filled family. These betrayals deepen Cassandra's distrust and sense that something is very wrong.

Seeking comfort from her boyfriend Robert, Cassandra experiences a vision of the model being murdered. The dream seems to prefigure a real crime, and soon she becomes a suspect herself. The line between dream and reality grows dangerously thin.

Cassandra's vision proves true as the model is murdered, and soon Stephen is killed while Helen is terrorized. The family is shaken, and Cassandra finds herself under suspicion for the deaths. Violence escalates rapidly around the family home.

Helen confesses to the police that Cassandra has a twin brother named Warren, who was institutionalized after Jill's death. She reveals that Jill is Cassandra's real mother and that Stephen and Jill had an incestuous relationship. The family history is exposed, reframing every prior event.

Helen explains that Warren has likely been released from the hospital and is seeking revenge. The idea of a living, vengeful twin shadows the contemporary danger, confirming that the past is not finished haunting the present.

Cassandra returns to the old family home where Jill died and encounters Robert, who reveals his true identity as Warren. The revelation reframes the danger as a confrontation with her own living twin brother.

Warren admits he killed their parents to stop the cycle, and Cassandra escapes before she shoots him, ending the immediate threat. She also sets the house on fire to erase the tainted family legacy.

Cassandra shoots Robert, who is revealed to be Warren, and sets the house ablaze to ensure the murderous cycle cannot continue. The fire consumes the home as the danger seems to be ending for now.

In the final moments, Cassandra realizes she shares a psychic connection with her brother. The nightmare about fire is exposed as prophecy coming true, and a mirror shatters as Warren reaches out, suggesting he may still haunt her future.
