Menjelang Magrib

Thalia, Erlan and Ahmad are psychology students doing research for a thesis on a psychiatric patient named Nina, who had been chained in a small hut. Nina`s mental disorder causes her to perform irrational actions. The disorder always appears before dusk and will stop before the Magrib prayers, so she must be tied down at those times. While conducting their research, the three students enter a terrible and dangerous situation without realising it because there are supernatural spirits around.
