Antonio Martínez is an old-fashioned cab driver who rides around Madrid, boasting about his children: Juan, who shares his job as a cab driver; Luisa, a ladies' hairdresser, Antoñito, who is studying to be a lawyer, and Paloma, who is going to be a housewife. But what Antonio does not know... yet is that his children are not exactly the way he thinks: Paloma who wants to marry a city policeman (a living nightmare for the poor driver !); Juan who is a cheeky guy leading a dissolute life; Antoñito who wants to be a bullfighter; and Luisa, who is a... go-go girl.The day Antonio finds out, he confronts his wife and children and suffers a great disappointment. Since then no one in the family speaks to Antonio, and he thinks it best to leave them to see for themselves that they have made a mistake, but this will not work either, since each one will see their problems increase.—Guy Bellinger

Taxi driver Antonio discovers one day that each of his children have been hiding their true way of life. He will try, with a typical hard attitude, for them to obey him, despite not being totally sure if his methods are the right ones or his teaching is appropriate.
