Lázaro and Sabino, employees of a large furniture store, fall in love with Laura, a new young and naive employee, who accepts their love. The trio lives a happy engagement. In the big store is planned a sensational advertising campaign with the bed "Eternal happiness," to be launched on New Year's Day. Lázaro and Sabino have to give the last touches on New Year's Eve. When they leave, they enter the exhibition truck and lie down on the bed. When they wake up in the morning, they are surrounded by a crowd and a scandal is organized.
