Natalia is a young Spanish woman who arrives in Mexico City, invited by Esteban, her boyfriend. However, due to work, he is absent, but his friends, Ana and Sofia, convince Natalia to travel to Valeria's house which is out of town, as a sort of bachelorette party. What starts out as an innocent comedy becomes an unusual and violent drama that questions the nature of power, the animality of our species, and the transposition of gender roles. 　　译文(2): 娜塔莉亚是一个年轻的西班牙女人谁抵达墨西哥城，邀请埃斯特班，她的男朋友。然而，由于工作原因，他没有出现，但他的朋友安娜和索菲亚说服娜塔莉亚去瓦莱里娅的家旅行，作为一种单身女郎派对。一开始只是一部单纯的喜剧，后来变成了一部不同寻常的暴力剧，质疑权力的本质、人类的动物性以及性别角色的转换。
