Monica and Annalisa Zero are twin sisters, but physically very different.

Annalisa has been working as a model since the age of 15 and is quite well known in the environment.

Monica is studying foreign languages at the University of Milan and has not yet decided what she will do in her future.

The sisters live together in Milan in an apartment owned by Renza, Annalisa's agent, who hosts the girls without demanding a rent.

Renza takes advantage of her generosity, initially demanding a reduced fee for the work entrusted to Annalisa, later to hook up Monica as well.

Renza is in contact with a well-known Venetian entrepreneur, owner of several shopping centers scattered throughout Italy.

The woman seems very interested in hiring the two girls, but her goals are not clear.
