Demasiado viejo para morir joven

Barcelona: two friends just find any temporary jobs to get by. One of them quits his job as a waiter to move to work as a messenger; the other is working as a taxi driver. The messenger, in his comings and goings at night, go through many offices, private homes and bars and will be in the most varied situations: some of them dark, sometimes sinister and pathetic and some even pleasant.
