Brady and Boomer are banned from the beach by the top surfer who is known as "The Big Kahula" whose also known as Hibachi. After being banned from the beach they return and they make an impossible bet with Hibachi that they will beat him in a surf competition and take back the beach. Hibachi states that if he wins, then no one will be able to surf on the beach again, but him and his friends. Brady and Boomer enlist in a boot camp run by Mason, who attempts to train them so they can learn how to surf, and take the beach back. Mason was formerly the top surfer, but was beaten by Hibachi, because he was blinded by what he assumed to be the sun. Brady and Boomer train and take on Hibachi, while Mikayla decides to keep an eye on Hibachi's friends. She discovers that they were trying to cheat by shining light from the sun into the eyes of Brady and Boomer by using a reflective shell. She puts the ones responsible to sleep with darts. Brady and Boomer win the competition, and Mikayla tells her father that Hibachi tried to blind them, and that is why Mason lost to him 10 years prior. Hibachi then runs away. Brady and Boomer declare Mason the new "Big Kahula" making him the top surfer of Shredder Beach.
