Widowed and with a young son in his charge, García works as a publicity agent in a razor blade factory. One day, taking advantage of the cycling tour to Spain, García puts into practice a new and risky system of advertising. But Mr. Raúl, the factory manager, does not like the idea and dismisses him. From then on, García will make a living in the most varied jobs: barber, shoeshine or guide of the Prado's Museum, a difficult situation for his former boss to accept the relationship he keeps secret with his daughter Conchita.
