Episode 4 of Back to 15 Season 2 opens with a vibrant atmosphere at the SISET
school, as the Interscholastic Games day commences. Anita captures a
heartwarming moment, photographing her father playing the guitar before his
much-anticipated checkup. As the sisters arrive at school, they encounter Joel,
dressed in a quirky meerkat costume, a result of a deal he's made to skip PE in
exchange for good grades. Meanwhile, Henrique, already a local celebrity due to
his music video, attracts considerable attention from his fellow students.
As the interschool competitors arrive, Cé finds himself the subject of curious glances due to his choice of attire: a skirt. The boys' dorm proving too notorious for his liking, he decides to switch to the girls' dorm for the night.
The focus quickly shifts to the handball game, where Douglas presents Carol with a pre-game gift that takes an unexpected turn when a condom falls out of her bag. Eduardo, the mascot of Merit school, taunts Carol relentlessly, disrupting her game. As she is subbed off, Anita urges Joel to do something about the offensive chants. Joel, in his meerkat guise, responds with a clever twist on the "Bella Ciao" tune, inspiring his team to push forward and reach the finals. However, Carol remains dejected on the bench, refusing to speak to Douglas when he tries to reconcile.
Coach Lucia entrusts Anita with a motivational CD, which she takes to the library to watch. There, she encounters Henrique, who is also checking out his music CD. Together, they watch the video, and Henrique attempts to kiss Anita, only to be met with rejection. Upset, he questions her intentions, referring to her whiteboard. Henrique storms out, mistakenly taking the coach's CD instead of his own.
Later, Henrique finds himself alone with Carol, and their emotions escalate towards a near-kiss. However, Miss Beth interrupts the moment, forcing them to leave separately. The next morning brings new challenges as the handball team discovers that their jerseys have been mutilated, jeopardizing their game. Fabricio steps in to save the day, providing the team with new uniforms.
Henrique realizes his mistake when he discovers that he has sent out the wrong CD: the coach's motivational video is actually his music video for the band. Back at the game, Eduardo's taunts escalate, leading to a heated confrontation between Carol and Eduardo, resulting in Carol's ejection. Despite this setback, SISET emerges victorious, but their celebration is marred by a disturbing incident: Eduardo and his cronies attack Joel, stealing his costume and notebook, which contains Joel's predictions for the FIFA World Cup results from the future.
As SISET celebrates their win, Anita witnesses Luiza taking a phone call. Putting the pieces together, Anita realizes the devastating news: her father is no more. Overwhelmed by grief and a sense of urgency, Anita tries to save her future by posting another picture on the photoblog.
