Antonio and Vicenta have just married and are ready to start their life together with an unforgettable honeymoon trip, but it is only possible for them to go to Pamplona during the Sanfermines. They expected to spend a few romantic and lonely days, but they find a city crowded with strangers and they can't even find a place to stay for the night. Finally, the owner of a pension prepares a bed for them in the lobby, but they will have to wait for all the guests to return to lie down.
