Plot.
In the town of Seabrook, werewolves, humans and zombies live in peace. It's their last year at Seabrook High (their high school) and Addison has been accepted into Mountain College. Zed is pursuing an athletic scholarship at Mountain College and is hoping to join Addison in her college. During the night before a highly anticipated football game, where, should they win, Seabrook's going to have their first zombie/monster recruited into college, therefore bringing down a barrier for all other monsters, a UFO arrives and causes mass panic. Its alien passengers and 3 alien leader's called "A-Lan, A-Li and A-Spen". They arrived in search of an interstellar map to Utopia (their previous home was destroyed), a perfect new home for their species. To cover up their real purpose, they claim to be here to compete in the National Cheer Off, which Addison previously had organized. While being interrogated by the Z-Patrol, A-Spen finds a loophole so Zed can get into college by having an exceptional scholarship by improving his grades.
Willa, Wyatt and Wynter are extremely distrustful of the aliens,they think they are there to take what is there's. The aliens settle into Seabrook temporarily. The aliens interrogate the werewolves and scan their minds with their Luma Lenses. Eliza, who is currently interning at Z-Corp, the maker of the Z-bands, helps Zed with his scholarship. However, the aliens beat Zed's records, both athletic and academic, lowering his chances of entering college. Zed, in return for the aliens altering his report card, helps the aliens identify the moonstone, which they scan for coordinates and discover is lethal to them. A-Spen meets Addison, whom they reveal to that they are in love with Zed. At cheer practice, the cheer team is threatened after witnessing the aliens practice. The aliens are almost caught by the werewolves and head to their Mothership where Zed helps them with his knowledge of Seabrook, whereas Addison is mistakenly beamed up to the Mothership. A-Spen, A-Li and A-Lan reveal their true reasons for arriving in Seabrook. After fixing and watching the Scout's logs, they discover that the scout is none other than Addison's maternal grandmother, Angie. (Bucky, Addison's cousin, is not related to Angie, as he is related to Addison on her father's side.) 
Zed is nervous for his home college interview, which is the last thing he needs to overcome before figuring out if he is accepted in Mountain College or not. Addison's alien powers cause him to "zombie out" during his interview, causing his interviewer, Ms. Crabtree, to leave. Addison questions her identity as an alien, asking her mom about her grandma. The trio of aliens suspect that the Seabrook Cup, which is the trophy Angie created, now awarded to the winning team of the Cheer Off, which is crafted with materials from their home world, is their map home. Addison discovers this same thing soon after and realizes either the aliens win it or she does. The werewolves discover the aliens' mission and alert the Z-Patrol. Zed, after learning he was accepted into college, discovers the Z-Patrol's orders and tries to stop the aliens from competing in the Cheer-Off. The extraterrestrial team is disqualified, leaving Addison being their only chance of finding Utopia. The Seabrook Mighty Shrimp are victorious at the competition and win.
The werewolves crash into the cheer pavilion and reveal the aliens' plans. The aliens, Addison and Zed escape before Addison reveals to the town her alien heritage. Zed reveals his college news and the aliens realize that the coordinates to Utopia lie in Addison's DNA. Unfortunately, their map is dynamic, meaning they must take Addison to their new home. A conflicted Addison agrees to go. Zed offers to go with her, but it's impossible as he would be killed by their stardust energy within minutes. The day the aliens and Addison are set to leave for Utopia, the aliens' ship is critically damaged, so the werewolves offer their moonstone and Eliza states that they could charge the ship by filtering the moonstone's energy through their Z-Bands. Zed risks his life by interfering with the power of the aliens and the moonstone, though he survives. As the others race to exit the ship before it releases into space, Addison and Zed share one last kiss before he is beamed back to Earth.
A few days later, in a world without Addison, the group celebrates their graduation as the aliens compute their coordinates. Addison realizes where her grandma Angie wanted her species to live. The aliens then return to Seabrook. Zed, Bree, Willa, Wynter, Wyatt, Bonzo, Bucky and the Aceys celebrate their return. Afterwards, the aliens fully move in to Seabrook, along with several other monsters and creatures including vampires and merpeople.
During the credits, Bucky is shown boarding Mothership and activating it for launch, aiming to "bring cheer to the farthest reaches of the galaxy".
