Noah and his best friend Baxter Bu, Bu for short, are the world's best friends and do absolutely everything together, including skateboarding. They are like 2 peas in a pod, until Noah leaves Bu behind in the treehouse every day as Noah starts surfing with some local surfers. Bu is feeling left out and inadequate and is willing to do whatever it takes to get his best friend back, even if it means learning to surf on his own. On his quest to learn how to surf, Bu meets interesting characters along the beach that get him to believe he has no luck at all coming his way. All of that changes after Bu literally gets some sense knocked into him. At the end of the day Bu realizes what friendship and self acceptance are all about and at the same time learns how to hang ten.
