Brady and McKenzie "Mack",are high school sweethearts enjoying their time together surfing at the beach. Each time Brady mentions their best summer never ending, Mack looks guilty as if she is hiding something from him but he doesn't notice it. After coming back inside McKenzie's grandfather's hut, McKenzie sees that Brady is a fan of the film "Wet Side Story", a film set during the 1960s. In the film, bikers and surfers battle for which gang gets the privilege to hang out at Big Momma's, a local diner and hangout. Mack, however, does not like such shows, viewing it as silly and illogical. Brady later learns that Mack made a promise to her aunt that after her mother died she would attend a private school and they were to leave the next day.
