Veteran Inspector Méndez investigates the death of a woman found on a tourist beach.

Victor finds his wife, Virginia, in bed with another man. Virginia is dead, and the two men decide to lie so as not to tarnish the memory of the deceased. The lover will disappear, and Victor will declare that Virginia died by his side. But the game of falsehoods will become complicated. Nothing will go as planned, and a new woman will appear who will make both of them lose their heads.

The adventures of four boys, two girls, and a monkey, facing off against a gang of youths from different social backgrounds, two police officers, and other secondary characters, create a mosaic of adventurous life with a surprising ending.
