Forgotten Island (2026) Story Breakdown & Ending Explained

DreamWorks Animation's "Forgotten Island" is a 2026 fantasy adventure that trades in dragons and ogres for something closer to home: the ache of watching a lifelong friendship change shape. Directed by Joel Crawford and Januel Mercado, the film follows Jo and Raissa, two inseparable best friends from the Philippines who are suddenly pulled into Nakali, a mythical island populated by creatures pulled straight from Filipino folklore. What starts as a farewell adventure on the eve of Raissa's move to America quickly becomes a race against time, memory, and heartbreak. Below is a complete, spoiler-filled, start-to-finish recap of everything that happens in "Forgotten Island," along with a full breakdown of the timeline, the characters, and what critics are saying about the film.

Childhood Beginnings in the Philippines

The story opens in the Philippines during the 1990s, where a young Jo stands in front of her classroom telling a spooky tale about the forgotten island of Nakali and its most feared resident, the Dreaded Manananggal. When a classmate mocks her story, Jo lashes out and lands herself in the principal's office. There she meets Raissa, who got in trouble for defending her. The two instantly click, and a lifelong friendship is born.

Bracelets, Bedtime Stories, and a Grandmother's Legacy

Raissa is soon invited over for a sleepover, where Jo's grandmother, Lola Fatima, delights the girls with stories about her own long-ago journey to Nakali. Inspired, the girls create matching charm bracelets that they fill with keepsakes representing their favorite memories together. Years pass, the girls grow up side by side, and eventually Lola Fatima passes away, leaving Jo with the island's legend as one of the last pieces of her grandmother she has left.

Graduation Day and a Painful Secret

As the girls reach the end of high school, Raissa breaks the news that she's been accepted to Caltech in the United States instead of a local college. She tells Jo it was her parents' decision, though this isn't the whole truth. During Raissa's farewell party, Jo overhears Raissa's mother making disparaging remarks about the two girls' friendship, adding fresh hurt to an already painful goodbye.

One Last Night, a Magic Sand Dollar, and a Portal to Nakali

Wanting one final night together before Raissa leaves, the girls sneak off to the beach. An argument breaks out between them, and in the middle of it, Jo discovers a glowing, magical sand dollar buried in the sand. The object tears open a shimmering portal, and before they can process what's happening, both girls are pulled through it and disappear from the beach.

Waking Up With No Memory

Jo and Raissa wake up hours later on the island of Nakali with absolutely no memory of what happened after they stepped through the portal. This missing night becomes the central mystery driving the entire film. Confused and disoriented, they're greeted by Raww, an eager but accident-prone weredog (a "were-aspin" pulled from Filipino mythology) who offers to guide them across the island so they can find a way home before Raissa's flight to America departs in just five hours.

A Journey Through Nakali's Mythical Creatures

Guided by Raww, Jo and Raissa venture deeper into Nakali, encountering a colorful cast of mythological figures along the way, including the wily Bungi Tiyanak, the commanding Datu, the boastful King Truffle Wuffle, and the charming Prince Mermahn. Some of these figures become valuable allies, while others complicate the girls' journey home. Throughout their trek, the looming threat of the Dreaded Manananggal, a terrifying winged creature known locally as Manang, hangs over every step they take.

Batiba's Bargain and a Devastating Revelation

The girls eventually cross paths with Batiba, a memory-trading figure who reveals a shocking truth: she had already made a deal with Jo and Raissa the night before, exchanging their memories of Nakali for a way home. This explains why neither girl can remember what happened after the portal opened. When the girls lose the magical sand dollar needed to activate the return journey, Batiba seizes the opportunity to offer them something else entirely: their missing memories, stored inside a lost Polaroid camera.

In a trance-like flashback, the truth comes out. After Raissa impulsively stole one of Manang's wings the night they arrived, Jo secretly hid the sand dollar so the two of them couldn't return home right away. She simply couldn't bear the thought of losing Raissa to Caltech and wanted more time with her best friend, even if it meant erasing their memory of that first night together.

The Fallout Between Jo and Raissa

Raissa is furious. In the heat of the argument, she finally admits that going to Caltech was her own choice all along, not her parents'. Feeling betrayed and manipulated, Raissa storms off alone to retrieve the sand dollar, effectively ending their friendship in her eyes. At the same time, Manang launches an attack, determined to reclaim her stolen wing after learning that Batiba stole one of her own memories as well.

Raissa's Confrontation With Manang

While searching for the sand dollar near Manang's cave, Raissa finds it, but Manang catches her in the act. Cornered and desperate, Raissa reveals to Manang that Batiba has been stealing memories from her too, not just from Manang. The revelation stuns the creature and briefly halts the confrontation, giving Raissa the opening she needs to escape.

Jo's Ultimate Sacrifice

Jo arrives to help Raissa get away from Manang safely, but before the two can escape together, Jo reveals she has struck yet another deal with Batiba. To guarantee Raissa's safe return home, Jo agrees to give up her own friendship bracelet, the very object holding her memories of their bond. Raww attempts to intervene and save Jo, but he fails, and Jo becomes trapped on the island as Raissa is pushed back through the portal alone.

Alone on Both Sides of the Portal

Raissa lands back on the same beach where their adventure began, overwhelmed with regret and grief over how the night ended. Meanwhile, back on Nakali, Batiba begins the ritual to absorb Jo's memories completely, threatening to erase every trace of her friendship with Raissa forever.

Love Pulls Raissa Back

Unable to live with the outcome, Raissa discovers that her genuine love for her friendship with Jo is powerful enough to pull her back into Nakali without needing the sand dollar at all. She races against time to reach Batiba's lair before the ritual finishes and Jo forgets her entirely.

The Climax: Stopping the Ritual

Raissa arrives just in time and successfully disrupts Batiba's memory-draining ritual, saving Jo's memories and, with them, their friendship. Manang, now aware of the full truth about Batiba's memory theft, storms into Batiba's lair herself, having come to understand just how much power memories truly hold. In the resulting chaos, Raww, Bungi Tiyanak, Prince Mermahn, and a giant bird team up to hold Manang back while the situation is finally resolved.

Reconciliation and Resolution

With Batiba's scheme stopped, tensions ease across the island. Manang, having recovered a piece of her own lost past, softens considerably and vows never to steal another creature's memories again, though the film pointedly never reveals exactly what memory she lost in the first place, leaving it as one final, lingering mystery. Jo and Raissa reconcile, their friendship stronger for having nearly lost it, and the whole group gathers for one last photo together before the girls finally return home for good.

Epilogue: Years Later

The film jumps ahead to adulthood, where Jo travels to Caltech to promote a new book she's written, a fictionalized retelling of their Nakali adventure that places Raissa at the center of a love triangle with book versions of Raww and Prince Mermahn. After the event, Jo tells Raissa she has a flight to catch, but the two realize they have just enough time for one more detour. Using their friendship bracelets, they open a portal to Nakali right in the middle of a university hallway, confirming they can now travel back and forth between their world and the island whenever they choose.
