This is the true story about a young Satanic sect in Italy, intertwined with extreme metal music, a band and a group of friends who went too far—far beyond the point of return.

The sect known as the “Beasts of Satan” committed a series of brutal ritual murders and other depraved acts. As tension within the group grew, members became afraid that others might inform the police—and they took action to silence them.

They buried one friend alive, forced people to set themselves on fire, shot the band’s drummer, hanged one classmate at school and more. The case spiralled completely out of control and reached all the way to the Vatican, which later renewed exorcism training for priests.

The sect was suspected of as many as fourteen additional murders, although those cases could never be proven due to insufficient evidence. The known members received long prison sentences, yet some have since been released. We are in contact with one of them...

At the heart of the film is also the story of a father who never gave up searching for his son, who had been murdered by the sect.
