When the pregnant Esther gets some bad news from her doctor, he advises her to visit a clinic in Mexico City, so she enlists husband Antonio to drive her there at once, along with her brother Luis. As soon as the men drop her off at the hospital, they hit a local nightclub and live it up, and as they are leaving the club in the company of a sexy dancer, they get thoroughly robbed: the criminals even steal the poor victims' clothes! Taken in to the police station and documented along the way, their photograph turns up in the paper the next day, which Esther of course sees. The men will have a lot to explain when they arrive at the clinic to pick up Esther.
