Las razones de mis amigos (2000)

Santiago, Marta and Carlos meet once a month to eat together, always in the same restaurant. They have known each other since university, more than 15 years ago. Then they shared many dreams and illusions, but over the years each has followed his own path. In one of those meals, Carlos borrows four million pesetas from Santiago and another four from Marta because his computer company has problems with a project they are developing. Months go by and Carlos can't get their money back. Santiago and Marta assure him that it does not matter, but in reality their lives have changed since that meal.
