Over the course of one hot summer’s day in rural Argentina, two sisters grapple with teen angst and self-discovery. Lucía (Melisa Romero) and Elena (Florencia Decal), are stranded in their parents’ modest small-town home as the day begins. While the younger whiny and spoiled Elena is laid up in bed with a broken ankle, Lucía heads out early to a local swimming pool. As the day progresses, each girl chooses her own adventure: Lucía meets up with Ana (Sol Zavala), a quiet girl her age with whom she gradually forms a very special bond; and Elena weasels her way into accompanying her older male doctor on some calls, eventually awkwardly exercising her burgeoning sexual prowess.
Documentary-style imagery aptly captures the sweltering atmosphere of the surroundings, as well as the girls’ slow and stumbling climb towards adulthood as they navigate their relationships with those around them.
