Mauricio organizes a mus championship at the bar. The owner of the 'Reinols' has always managed to win all the editions he has held previously. However, this time the person who always played with him will not be able to do so, and this forces Mauricio to have Luisma as a couple. In the final, the two face Chema, and before Luisma's incompetence, Mauricio resorts to cheating to win the winner's cup again.
