Eva Sagarrondo es una famosa escritora de libros de pareja, quien ya no cree en el amor para siempre... y está dispuesta a probar que su teoría de que la relación ideal para la mujer moderna es ponerle fecha de expiración al romance -- y así evitar corazones rotos. Adam di Melo es un italiano romántico que está en México gracias al amor -- ¡pero con el corazón roto gracias a los libros de consejos de Eva! Juntos se embarcarán en una aventura de 31 días que cambiará la vida y la visión del amor que ambos tienen. 31 Dias (31 Days) is the story of Eva (Irán Castillo), a young and beautiful psychologist and author of a series of self-help books about modern women and their love relationships. For her next bestseller she has decided to prove her most daring theory: After the first 30 days together love ends, so the only way to have a meaningful relationship in this new millennium is to for the couple to part ways after the first month. At a magazine's photo session Eva meets Adam (Lorenzo Balducci), an attractive Italian photographer, and she decides he's perfect as her study subject. She will live a very intense relationship with Adam during 31 days, in order to prove her theory is right. However, what she is not aware of is that Adam is using all her own advice from her books in order to make her fall in love with him and teach her a lesson. What neither of them suspects is that they'll come to learn that love has no rules. ------------------------------------------------------------------------------------------------------------------------- RATINGS: IMDB: 6.6
