Don't be surprised if the Mexican television broadcasts this movie on New Year's Eve. Because this story begins that night.
This is a funny comedy starred by Pedro Infante and Silvia Pinal; Cruci and Mané. They have never met each other but when Mané's car breaks on the road, after a quarrel with her fiancé, Cruci is the mechanic who comes to help her. None of them wants to spend a lonely New Year's Eve so both come to Mané's place. Dancing, playing and drinking and more drinking the night goes by. So next morning they are caught together on bed by Mané's family. But what really happened? No embarrassing questions please: they are forced to marry.
Cruci is a loser, an ordinary mechanic while Mané is member of a wealthy family. Cruci's real name is the most ridiculous you can hear: Cutberto Gaudázar. So he is forced to change his name from the very first night to Cruci. To avoid shame when Cruci is introduced into society he is no more a Mexican mechanic but an European aristocrat. And so on, helplessly, step by step, the couple leads to the prearranged divorce.
But ¡Alas! Should she fall for a mechanic?
This movie had a remake, Romeo contra Julieta (Romeo vs Julieta) starred by Angélica María and Alberto Vázquez, which is almost forgotten even by the Mexicans.
