One day, three young seamstresses who love nightlife and fun, upon returning to the house they share, find a seriously injured girl in the bathroom.

When the pieces of a singular figure are unearthed and then joined together, a devil of the lowest category breaks into a small Mediterranean village. From that moment on, the demon will enter the life of a painter named Bernardino, in the affairs of a "modern" marriage, in the existence of a frightened gardener and, finally, in the day-to-day life of the Great Momo.
