He is a peculiar and shy boy with no sentimental experience and inevitably falls in love with Eva, the first woman in his life. While Camilo tries unsuccessfully to win her heart, Eva turns the world of the Jose Maria Root Public School upside down, teaching her classmates all about sex, love, pleasures and real life. Yet, Camilo discovers that Eva keeps a deep, dark secret that could separate them forever, and now he will have to fight not to lose what could be his first romantic experience... his first and great love.
