Paula and La Maestra are 16 and inseparable. The strongest swimmers on their team, they are training together over the summer to represent Mexico at the Junior Pan American Swimming Championships. One night at a party, Paula ends up alone with Daniel, a good friend and her long-time crush. Amid reggaeton, flirting and shots, Paula and Daniel slip into the bathroom together. Soon after, La Maestra senses that something has changed. Paula seems distant and deeply sad. At first, she insists nothing is wrong, but La Maestra keeps pushing until her friend begins to talk about what happened that night. Searching for answers, they try to name the experience, and what they find feels devastating. As the two girls respond in different ways, their bond is put to the test. Paula needs time, while La Maestra feels compelled to speak out. Fear, feelings of guilt and anger begin to fracture their friendship, pushing them towards a decision that will redefine who they are, together and apart.
