In Seabrook, a town where werewolves, humans, and zombies have learned to share the same streets, the mood at Seabrook High is buzzing with the last big year for its senior class. Addison has just earned a place at Mountain College, while Zed is chasing an athletic scholarship with the hope of joining Addison there. The looming football game looms large: win, and Seabrook could see the first zombie or monster recruited into college, smashing a barrier that once kept their kind on the sidelines. But the night before the big game, a sudden UFO streaks across the sky, sparking mass panic and pulling everyone into a new, tangled set of revelations.
From the moment the alien ship touches down, the town is put on notice. The visitors—A-Spen, A-Li, and A-Lan—step into Seabrook with a mission that’s slyly cloaked in innocent competition. They pretend to join the National Cheer Off, a scene Addison has long organized, in order to hide their true objective: locate an interstellar map to Utopia, a home for their species. Their claim of friendly rivalry is a cover, but their arrival shakes the established order at Seabrook and puts Zed’s future in jeopard as they push past records—both athletic and academic—to outpace local achievements. The aliens’ presence is met with suspicion by Willa, Wyatt, Wynter, and the rest of the town, who fear that the newcomers will take what’s theirs.
The plot thickens as Eliza, who is interning at Z-Corp—the maker of the Z-bands—steps into the fray to help Zed with his scholarship. Yet the aliens outpace Zed in every test, threatening his chance to study at Mountain College while still pursuing their own hidden agenda. In a surprising turn, Zed lends his intimate knowledge of Seabrook to the aliens so they can identify the moonstone—an artifact they scan for coordinates. The moonstone proves essential yet dangerous to them, and the aliens’ plan begins to hinge on Addison, whom A-Spen reveals is at the center of their quest: the map lies within Addison in a way that binds their fates together. As the school’s cheer practice intensifies, the aliens’ presence escalates from curious to threatening, and Addison, in a moment of crisis, is accidentally beamed up to the Mothership.
Amid the escalating tension, the aliens unveil their true intentions. They reveal what they’re searching for and the strings that tie Addison to Utopia. A key discovery comes from scouring old scout logs, which leads to a startling revelation: the supposed scout is Addison’s maternal grandmother, Angie. The town’s news cycles and the high-stakes competition collide in a way that shifts the entire dynamic of Seabrook. The werewolves mobilize, the Z-Patrol closes in, and a race against time unfolds as Zed learns of the Z-Patrol’s orders and takes action to stop the aliens from competing.
A crucial moment arrives during the Seabrook Cup, the trophy crafted from materials from the aliens’ home world. Addison realizes that she must decide whether to let the aliens win in order to reveal the truth or to gamble everything on keeping the map’s location safe. When the aliens are disqualified from the Cheer Off, Addison becomes the town’s last, best chance to locate Utopia. Her performance, combined with the team’s victory by the Seabrook Mighty Shrimp, tips the scales in an unexpected direction, and the town breathes a collective sigh of relief as the aliens’ plan comes undone—at least for the moment.
The showdown erupts as the alien ship makes its final approach toward leaving Seabrook. Addison finally reveals her alien heritage to the town, a truth that has been simmering beneath the surface. Zed learns that the coordinates to Utopia are embedded in Addison’s DNA, and the revelation forces a heart-wrenching choice: the map can be accessed only if Addison goes with the aliens to their new home. Zed offers to accompany her, but the cosmic reality is brutal—his life would be in mortal danger due to the ship’s stardust energy. In a dramatic finish, the ship is damaged, and the Moonstone’s energy is redirected to power a risky charge through the Z-Bands. Zed makes a perilous move to intervene, survives, and the couple shares a final, tender kiss before Addison is beamed back to Earth and the spaceship vanishes into hyperspace.
Days pass in a world without Addison, yet graduation brings a sense of cautious optimism. The aliens decrypt Addison’s DNA, confirming that their map’s coordinates point to Earth all along. Angie’s role as the grandmother who was guiding them is understood, and Seabrook’s townsfolk begin to reimagine their future. The aliens return to Seabrook, welcomed back by a community that has learned to accept monsters and legends as part of everyday life. The town’s celebration continues with a chorus of new possibilities as the aliens integrate and a growing constellation of creatures—vampires, merfolk, and others—find homes alongside the humans and monsters who call Seabrook home. The film closes on a note of bright, communal celebration and curiosity about what tomorrow might bring, even as a final image hints at the continued reach of the Mothership’s mission, now prepared to launch again to spread cheer to distant corners of the galaxy.
Performances feature Mariano Oyarguren, Pablo G. Pérez, Maria Mercedes Eliçabe, and Mariana Brangeri, bringing to life the quirky, brave, and sometimes stubborn residents of Seabrook with warmth and energy.
