An ancient urn chained to a coffin is unhearted by chance by some men at work along the road bordering the Viterbo’s cemetery. The urn contains an age-old tunic and some objects belonging to Mater Lacrimarum, the Third Mother (Moran Atias). The only survivor of the Three Mothers - three powerful witches who had been shedding blood and terror for aeons - Mater Lacrimarum (the Mother of Tears) has been hiding in Rome for centuries and her awakening triggers a chain of mysterious and terrible events: the Evil is back to cast its dark shadow over the city.
