Starring are Ross Lynch and Maia Mitchell as Brady and McKenzie, surfers who take the last wave of summer, one that mysteriously takes them into a classic beach party movie, Wet Side Story. There, it’s surfers versus bikers for control of the beach hangout…and everyone spontaneously breaks into song and dance. Brady and McKenzie must try to return to present day, but their lives may be changed forever when they inadvertently change the movie’s romantic storyline — and the movie’s handsome surf guy, Tanner, is falling for McKenzie while biker girl Lela is swooning for Brady.
