Four siblings, Saleh, Fajar, Tyas and Azizah, have heard stories about heaven and hell since childhood. They were educated strictly by their father, a young ustad who was well respected in the village. One night, on their way to the opposite village without their parents knowing, Saleh and his younger siblings were swept away by a strong river current and disappeared. Saleh then woke up in another realm, the hell that his father always talked about. A search is carried out in the world to find the father's children, whether alive or dead. One by one the secrets are revealed, making fathers and mothers question whether they are providing enough for their children. In hell, Saleh and the others also look for each other, while facing increasing torment for the sins they have been hiding.
