As the youngest child, Tasya (Gabriella Quinlynn) has never known her mother. Unintentionally, she watches an old videotape owned by her father, Ferdi (Lukman Sardi), who communicated with her mother's 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 occult.
