The fancy El Castillo Hotel is about to go bankrupt and only a good injection of capital can save it. The foreign man that is interested in this business is mistaken for Primo González, a humble guy that arrives in that moment to work there as a waiter and who decides to play along with the misunderstanding, because he falls in love with the Manager. When Eduardo Sánchez, the real investor, finds out about the mistake, he decides to take the job as a waiter to analyze if investing in the hotel is actually a good business for him.
