A PE teacher moves to a isolated mountain village where the people appear to live in unshakeable serenity, but soon stumbles across a disturbing ritual. Once a week, the locals are freed of their pain by a lonely boy born with the power to heal one's soul just by hugging them. Trying to rescue him from this madness, the man unleashes his dark side.

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.
