Late at night in a Malaysian camp, a group of female trainees on duty are urgently summoned. One trainee, allegedly possessed by a ghost, accuses them of breaking the rules by leaving "dirty things" in the toilet. The instructor sternly orders them to clean it up by midnight. These girls, from different faiths, are placed in the same living space, and the boundaries of mutual respect start to blur, with their strained harmony on the verge of collapse. They are pressured to undertake a gruesome midnight cleanup.
