A dark legacy draws Cabbar and a cursed family into the depths of a mansion haunted by centuries-old secrets and uncanny entities. Cabbar, a chosen spirit, is the last representative of a dhikr tradition that dates back to the Ottoman era. His talismanic armor and powerful dhikr are his only weapons in his battle with the demon world. But this time his struggle is personal: The secrets waiting to be unraveled within the walls of the mansion are woven with the betrayal of the cursed. When Hasan moves into the mansion he inherited, he does not heed the lawyer's warnings. His daughter Elif wakes up in the middle of the night to the whispers of children in her room, while his wife Esma is driven to the brink of madness by the bloody silhouettes she sees. The sadness in the eyes of Mrs. Asiye, the guardian of the mansion, whispers the truth. As the curtain of mystery at number 303 is lifted, Cabbar will pay a heavy price for his struggle to save his family.
