Phoenix ultimately reveals that the spirits haunting the house are connected to Anna Rose, a young woman who was presumed dead during a cholera outbreak in 1971. Anna and her lover Freddy were deeply in love, but their relationship was opposed by their families. Amidst the chaos of the epidemic, Anna contracted cholera and was believed to have died. However, she was still alive, having been buried alive in her backyard in a grave marked by a string tied to her finger, a cautionary practice from Europe designed for people buried alive. Anna's spirit remained trapped, unable to move on, and she started haunting the house, trying to reconnect with Freddy. Unaware of her survival, Freddy thought Anna had abandoned him and married someone else, falling into a new relationship with Margaret.
As the story unfolds, John, the protagonist, uncovers Anna’s tragic fate through old records and a priest, Father Francis. It becomes clear that Anna’s spirit is seeking closure and reunion with Freddy. When John finds Freddy’s address, he hopes to fulfill Anna’s wish by reaching out to him. Although Freddy is initially unavailable, his mother shows up instead, and John delivers Anna’s letter. This act awakens Anna’s spirit, which then manifests as a vengeful ghost that possesses John’s daughter Mariya, causing her to self-harm and threaten the family.
As the climax approaches, Freddy finally comes to the house, having believed that John’s letters might be from Anna. When Freddy sees Anna’s letter, he recognizes her tragic story and understands her desperation. In a moment of emotional confession, Freddy finally meets Anna’s spirit through Mariya. Freddy is overwhelmed with guilt for having abandoned her and realizes that Anna’s spirit is punishing him for neglecting her love. Anna’s spirit, empowered by her death and her desire for justice, makes Freddy feel her loneliness and despair. In the end, Freddy’s return to the house is her way of finally reuniting with her beloved, and through this connection, she is able to rise from her grave like a phoenix—symbolizing her rebirth and the fulfillment of her love beyond death.
