The story centres around a teenage boy named Badrol, who visits his grandpa Tok Dalang in a village called Kampung Durian Runtuh. But something disturbs the peace there. Villagers tell of a fearsome beast lurking at night but no one dares to find out what it is until Badrol, his friend Lim, Rajoo, and two adorable village twin boys Upin and Ipin stumble upon the very heart of the mystery itself.
