Catrasca (Jorge Porcel) is a man who works in a restaurant and in his spare time helps in a children's home. His problem is that he carries a family tradition that makes him cause catastrophes in his path, one of which takes his boss (Adolfo García Grau) to the hospital.
Upon leaving the hospital, Catrasca is run over by Graciela (Graciela Alfano), the daughter of Professor Galíndez (Osvaldo Terranova). This is how he meets this professor, who has a formula that says he will be the salvation of humanity, so he is the object of persecutions by villains such as Dr. Linda Winters (Moria Casán).

His wife, Carmen, an attractive housewife without children, it feels ignored by him and seeks solace from her mother, who proposes Carmen a change in the way she acts in order to do not lose permanently her husband or even fall into madness.
