Waves and high tides were all teen surfer Mckenzie lived for. Mckenzie wanted to spend her last summer with her high school boyfriend Brady. Unbeknownst to Brady, Mckenzie is leaving for boarding school soon after promising her aunt that she would get serious about her education. A few hours before Mckenzie's flight she plans on catching a couple of waves.

Suddenly one huge wave in particular knocks Mckenzie off her board into the ocean. Brady is not far behind and tries his best to save Mckenzie from the violent current, but the two are both submerged under water. After waking up Mckenzie and Brady both find out that not only have they traveled to another beach, but to a new dimension as well and they are now a part of Brady's favorite movie, "Wet Side Story" based in the 1960s where it's bikers versus surfers for full control of Big Mommas, a local hangout spot.
