As the youngest child who has never known her mother, Tasya (Gabriella Quinlynn) feels lonely. Unintentionally she watched an old videotape owned by his father, Ferdi (Lukman Sardi), who had communicated with her mother's deceased spirit using Jailangkung. Tasya assembles her own Jailangkung and plays it in hopes of communicating with her deceased mother. This incident apparently raised various problems, including a catastrophic spirit. Bella (Amanda Rawles) and Rama (Jefri Nichol) join their new partner, Bram (Naufal Samudra), on an adventure to the bottom of the sea to defeat the demon incarnation that rules Angel (Hannah Al Rasyid) and takes Tasya to the occultddd
