In the same house, on the same night, two groups meet. One, made up of very serious gentlemen, members of a religious-monarchist order. The other, a bunch of crazy people in animal costumes, at a party with sex and rock’n’roll. When the storm starts and the lights go out, anything can happen.

Julius is a photographer working as a men's magazine photo retoucher. His wife, Marcia, is a criminal lawyer who defends Teodoro, a squatter accused of murder. For years they had a quiet wedlock. However, Marcia gets involved with her client, and as revenge, Julius sleeps with Ana Maria, a friend of their daughter Guida. From this episode on, their lives are no longer the same.
