介绍：若然未报，时辰未到，报应始终会来　　五名好友因一时疏忽造成了一起严重车祸，他们决定一起毁尸灭迹掩盖真相。一年后，一个知晓该事件的神秘杀手在暗处伺机夺取他们的生命，而他们发现相似的事件曾在数年前发生过，他们决定向当时的两位幸存者 (詹妮弗·洛芙·休伊特、小弗雷迪·普林兹 饰) 求助。

介绍：Nothing is more frightening, as the narrator points out, than a ‘time-rich nosy person’. Exhibit A is Ahn Geo-ul (Gyeong Su-jin), who commits herself to social justice causes with terrifying tenacity. After temporarily renting a unit in the Baek-sae Apartment building, she discovers that a loud, hard to locate banging noise occurs from 4am every night, making the residents’ lives an insomniac hell – and so she determines to engage in her own disruption and to find the culprit of this acoustic assault, simultaneously eliminating her eccentric neighbours as suspects, and recruiting them to her cause.　　Focusing on a woman who is an unstoppable force for good, it is also a plea for community cohesion and solidarity.
