To rescue his daughter, an unstable Special Forces veteran unleashes his inner beast as he pursues her kidnappers — and soon becomes a suspect himself.

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.

Three well-off young men—former students at Rome’s prestigious all-boys Catholic high school San Leone Magno—brutally tortured, raped, and murdered two young women in 1975. The event, which came to be known as the Circeo massacre, shocked and captivated the country, exposing the violence and dark underbelly of the upper middle class at a moment when the traditional structures of family and religion were seen as under threat.
