靛蓝的夏夜，在一个炙热的的日本郊区，几个被隔离的人类和非人类发现自己身陷危险的光影游戏。一声尖叫声中隐藏的眼泪和欢笑撕裂了夜的沉寂。

One indigo summer night, in a rather tropical suburban Japan, several isolated humans and non-humans find themselves caught in a game of shadows and lights more or less threatening. At most a few tears, or a laughter hidden behind a scream, are tearing the silence of the night apart.
