After two mysterious deaths at a college on the same night, seven students, somehow connected, receive invitations to a confessional booth hidden on the campus. Their confessions slowly unveil the truth behind, not only the deaths, the booth as well. The dark, twisty, dialogue-driven and emotionally-complex mystery is entirely confined to the video confessional.。该片讲述了85岁高龄的林女士(金英玉饰)夹在扮演着孝子的儿子(金永敏饰)和如家人般的疗养护工(朴成妍饰)之间的故事。聚焦“像外人的家人”和“像家人的外人”,讨论了是因为家人而一起生活还是因为一起生活而是家人的现实问题。。
