En un claroscuro de la luna (1999) is a tragic romance involving an environmentalist who goes to the south of Mexico to wage war against that country’s major polluters, mainly the oil industry. Pollution isn’t the only thing on his mind, however, as he quickly becomes involved with the young and very beautiful daughter of a Russian immigrant. Arcelia Ramírez dances around in her unmentionables and flashes two delightful little tater tots.
