Susanna, a very unattractive woman, receives a dietary supplement as a gift from her friend Pamela. The Bonason are capsules which improve the self-esteem, and that should lead Susanna to take care of herself and improve her vision of life and world. After the last rejection from her colleague Samuel, with whom she is madly in love, Susanna decides to try the Bonason, but she takes too many capsules, so she finds herself transformed just a few hours later.
