On the eve of the first day of school, Brady and McKenzie celebrate the day they met and reminisce about the summer, while they watch Brady's favorite movie, Wet Side Story, the 1960s musical film that they got stuck in during the events of Teen Beach Movie. Mack dismisses Brady's fear that their relationship will change when they begin school. Mack then notices she lost the necklace she received while in Wet Side Story's universe. At school, Brady and Mack reunite with their respective friends, Devon and Alyssa, who are surprised by their new relationship due to their opposite personalities. Brady and Mack are surprised by how differently they act at school. Later, in class, Brady is working on surfboard designs, but hides them when Mack asks him what he is doing. Brady becomes defensive when Mack meets a handsome boy named Spencer Watkins. Mack works on a "Save The Beach" dance, despite Brady's attempts to see her. Struggling with a college application, Brady works on a surfboard instead and accidentally forgets about a college fair that he was to attend with Mack, upsetting her to the point that they break up. In the Wet Side Story universe, Lela and Tanner notice Mack's washed-up necklace and journey into the ocean, winding up on the same beach as Mack and Brady, who are still mad at each other. Mack and Brady tell Lela and Tanner that they are in the future, exciting them. Mack and Brady do not tell them they are film characters, choosing instead to show them that the real world is not as great as it seems, in hopes that they will return to their own world. Meanwhile, the characters in Wet Side Story are confused without Lela and Tanner. Brady and Mack bring Lela and Tanner to school, where their movie characteristics come out against Mack and Brady's cautions, culminating in a big musical number in the cafeteria. Lela becomes too enthralled with math homework to spend time with Tanner after school, and Tanner confesses to Brady that he worries he is not enough for Lela, while Brady reveals to Tanner that he and Mack are taking a break. He also shows Tanner his surfboards, and alludes that Mack might not understand his newfound hobby. Realizing they are becoming part of the future, Mack and Brady tell Lela and Tanner that they are just characters in a movie, showing them clips from Wet Side Story. Upset by this, Lela throws the necklace into the ocean, prompting Mack and Brady to search for it. This leads to another argument between them, which disturbs Lela and Tanner. In the Wet Side Story universe, characters begin disappearing out of thin air. One of the characters, Butchy, realizes that all of this started after Tanner and Lela left. Butchy notices the necklace washed up, and leads the gang into the ocean to get the two back. They enter the real world and inform the others about the disappearing characters. Brady and Mack realize that without the main actors, there is no movie. The movie characters return to Wet Side Story. Brady and Mack avoid each other during the "Save the Beach" dance. The characters of Wet Side Story return after deciding to reunite Brady and Mack. When Butchy disappears with the necklace, Brady and Mack run to get Mack's grandfather's surfboard, which they first used to get into the Wet Side Story universe. With no waves, Brady decides to use a motorized surfboard he created, along with the emblem from Mack's grandfather's surfboard. Mack compares Brady's hobby to her grandfather's surfboard passion, and they agree not to keep secrets anymore. Before Tanner and Lela leave, Mack tells Lela to make the movie her story. Brady helps Lela and Tanner after a surfboard malfunction. When Brady emerges from the ocean, he and Mack appear not to know each other; they later meet at the "Save the Beach" dance, which Mack says is themed after her favorite movie called Lela, Queen of the Beach. Lela followed Mack's advice and changed the movie, which now has more feminist tones but unintentionally erases the history between Brady and Mack, who luckily fall in love again.

Reception
The movie received mixed reviews from critics. Brian Lowry of Variety.com wrote that while the songs were generally great and the storyline was easy to understand, "Everything else is really just the storytelling equivalent of pulling taffy, trying to create enough impediments to keep the narrative clunking along until the next spontaneous outbreak of song. Thankfully, there's a great deal of talent on the screen, though the words generally sound far better when sung than spoken." R. Thomas Umstead of Multichannel News awarded the movie 3.5 stars out of 5, writing, "Much like Teen Beach Movie, the sequel is full of impressive dance numbers, often silly dialogue and toe-tapping pop music songs that will certainly appeal to the network's target 6-to-11-year-old audience. Still, Teen Beach 2 lacks a bit of the charm exhibited in the first movie, although that will not matter much to fans of the original." The film drew 5.8 total million viewers on its premiere night, becoming the most watched DCOM since its prequel Teen Beach Movie aired in 2013. In L+3, Teen Beach 2 delivered 7.5 million viewers and along with the weekend encore telecasts, totals 13.3 million viewers.
