五个拼车的人乘坐一辆房车，去往一个共同的目的地。夜幕降临之后车辆因为意外情况撞上了一棵树。当他们清醒过来时，发现自己身处荒郊野外。之前的公路已经消失，只有一片密不透风的森林和一个空地上的木头房子，那是一个令人毛骨悚然的邪教组织的家。

小镇一片寂静。呼吸声和几声狗叫打破了宁静。男女老少都突 然间陷入永久的沉睡中。教堂里的两个小童子军是这个沉睡的 世界中仅剩的清醒的人。

In the past few days Rome has been the scene of a singular event: when it rains, the manholes exhale a dense steam whose origin and composition is unknown. No one can imagine that whoever breathes in the mysterious substance will have to deal with what he/she represses, their darkest instincts, their anger. Not even the Morel family.
