Every year, in the middle of the Brazilian holiday season, CAOSS is held, a surfing championship that attracts thousands of tourists and hundreds of young people in search of the same dream: to become professional surfers. The event is very important because the team that wins the tournament has the passport secured to continue competing professionally on the official circuits. At the beginning of the series Rafa (André Lamoglia) escapes from the summer course imposed by his father, a great businessman, to pursue his dream of being a professional surfer and win the CAOSS tournament. Thus he manages to form his team made up of Billy (Bruno Astuti) and Jojo (Marino Cangucu) and which will eventually be called Juacas. The Red Sharks team will be the main rival in this championship.
