As extreme as the madness it explores, an emotional horror experience set in a version of Rome on the point of imploding. Horror thriller codes are applied to a family drama, exploring an increasingly hateful modern-day society wrestling with ever-greater pressures. 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 mist will have to deal with whatever they are repressing, their darkest instincts, their anger. Not even the Morel family.
