Melissa is a shy 15-year-old girl who lives with her mother Daria and her heavy-smoking grandmother Elvira, while her father is overseas working on an oil rig. She has a close relationship with her grandmother, but feels increasingly distant from her mother. On a summer afternoon, Melissa and her best friend Manuela attend a pool party at the home of Daniele, a wealthy, attractive boy from school, on whom Melissa has long had a crush. Daniele takes Melissa to a secluded spot, where they talk for a while before he has her perform oral sex on him. Despite the less-than-romantic encounter, Melissa's feelings for Daniele only intensify.
