Fans of "The Summer I Turned Pretty" are gearing up for a bittersweet farewell as the beloved series returns for its third and final season on Prime Video this July. The official trailer dropped on June 11, 2025, revealing a dramatic and emotional ride ahead, set to a captivating mashup of Taylor Swift's "Daylight" and "Red (Taylor's Version)."
Based on Jenny Han's best-selling book trilogy, the show centers on the complicated love triangle between Isabel "Belly" Conklin (Lola Tung) and the Fisher brothers, Conrad (Christopher Briney) and Jeremiah (Gavin Casalegno). Season 3 picks up two years after the events of Season 2, with Belly and Jeremiah still going strong and even planning to get married. However, as the trailer hints, the past refuses to stay buried, and Conrad's return threatens to upend their future.
In the trailer, Belly reveals to her mother, played by Jackie Chung, that she and Jeremiah want to tie the knot, a decision met with surprise and concern. "I'm sorry what? Belly, honey, you two are not ready for a commitment like this. You're talking about a lifetime," her mother cautions, highlighting the tension surrounding the couple's plans. Despite this, Jeremiah assures Belly, "We'll figure it out," underscoring their determination to make it work.
Yet, Belly candidly admits, "When I'm with Jer, everything is easier, but everywhere I go, there's a memory of Conrad." This lingering presence of her first love adds layers of complexity to her relationship with Jeremiah. The trailer captures moments of heated confrontation, including a physical altercation between the Fisher brothers, as Jeremiah tells Belly, "I see the way he looks at you," to which she insists, "This is you and me." But the question remains: can Belly truly move on from Conrad?
The season's storyline, based on the third book "We'll Always Have Summer," explores these emotional entanglements with depth. In the novel, Jeremiah and Belly briefly break up after he spends the night with another girl, leading to heartbreak before they reconcile and get engaged. However, the wedding is called off, and Belly studies abroad while exchanging letters with Conrad, culminating in a flash-forward where Belly and Conrad marry at Cousins Beach. The show's creators, including Han herself, have hinted that the series may diverge from the book's ending, adding an element of surprise for longtime fans.
Showrunners Jenny Han and Sarah Kucserka, who also serve as executive producers alongside Karen Rosenfelt, Paul Lee, Hope Hartman, and Mads Hansen for wiip, have promised a season filled with emotional highs and lows. Han told Entertainment Weekly that "each of the characters will be put through the wringer," ensuring that the final chapter is as gripping as the journey so far.
The cast returns in full force, with Lola Tung reprising her role as Belly, Christopher Briney as Conrad, and Gavin Casalegno as Jeremiah. Sean Kaufman and Rain Spencer return as Belly's brother Steven and best friend Taylor, respectively, while Jackie Chung and Colin Ferguson reprise their roles as Belly's mother Laurel Park and father John Conklin. New additions for Season 3 include series regulars Isabella Briggs and Kristen Connolly, along with recurring stars Sofia Bryant, Lily Donoghue, Zoé de Grand’Maison, Emma Ishta, and Tanner Zagarino.
Set at the end of Belly's junior year of college, the season captures her anticipation for another summer at Cousins Beach, a place filled with memories and emotional crossroads. Conrad is now studying medicine at Stanford, living in California, and pursuing his career, yet his feelings for Belly remain unresolved. As Belly navigates her future with Jeremiah, she must confront the past that refuses to let go.
The trailer's emotional weight is underscored by Belly's voiceover: "First loves are important. But they're not as important as lasts. I loved [Conrad] in a way that you can only do the first time around. But that is the past. Jeremiah is my future. This is the way it is supposed to be. He is The One." Yet, the final moments of the trailer suggest that the path forward will not be straightforward, featuring scenes of tension, a car crash, and Belly walking down the aisle in a white dress, leaving viewers eager to find out who she ultimately chooses.
Adding to the intrigue, cast members have spoken about the possibility that the show's ending may differ from the books. Gavin Casalegno told Us Weekly in 2023 that while he knows Jeremiah's ultimate fate in the novels, the show allows the story to unfold naturally, without forcing a predetermined outcome. Lola Tung echoed this sentiment, praising Han's commitment to storytelling that serves the narrative and keeps fans engaged with fresh surprises.
Beyond the finale, the series' universe may continue to expand. Vernon Sanders, head of television at Amazon and MGM Studios, revealed in 2023 that Jenny Han has exciting plans for the franchise, hinting at complementary projects that will build on the show's success.
Season 3 will be the longest yet, comprising 11 episodes released weekly starting July 16, 2025. This pacing allows for a deeper exploration of the characters' journeys and the emotional complexity that has made "The Summer I Turned Pretty" a fan favorite.
As the final summer at Cousins Beach approaches, viewers can expect a season filled with love, heartbreak, and the difficult choices that come with growing up. Will Belly find the happiness she seeks with Jeremiah, or will the pull of first love prove too strong to resist? One thing is certain: this summer will never be the same.
