In this Spanish coming-of-age drama, two teenage boys find their sexual awakening and liberty put to the test over the summer of 1999. Nico (Jordi Vilches) is a budding motorcycle mechanic who has been invited to stay for the season by his best friend Dani (Fernando Ramallo). Dani's parents have left for an Egyptian vacation, leaving the two boys with the run of a summer home over the course of ten days. After bouts of smoking marijuana, eating junk food, and drinking, the boys emerge in innocent sexual games, including "krampack," a Spanish euphemism for "hand-job." After their self-involved sexual escapades, the two begin to forge a sexual relationship until two local girls, Elena (Marieta Orozco) and Berta (Esther Nubiola), enter their lives and begin to take an interest in them. Dani still pines for Nico, with whom he has fallen in love, but Nico only sees their sex play as fun and becomes more involved with the prospect of female attention. When jealousy starts to consume Dani, he finds solace in an older man, Julian (Chisco Amado), whom he sees as a potential rebound for his feelings toward Nico, even though his heart may still lie with his friend. Krampack is adapted from a Spanish play of the same name by acclaimed Barcelona native Cesc Gay.
