Zombies 3 - Where someday can be today
Addison wants to go to Mountain College with Zed, but there's no zombies accepted to a college before. Though Zed is a star soccer player, going to college is still a long shot. Zed is going to play in a soccer competition, where recruiters from the college will be there too. It's his only chance to show off how good he is. Before the game starts, there's an alien invasion. A group of aliens marches in and say they are just here to join the national cheering competition organized by Addison. As they possess extraterrestrial strength, they can do the tricks easily. However, their goal is not to win the competition, they want to find out the location of the utopia. They were told that a map for reach to the utopia was hidden on the most precious thing in Seabrook, so they have been secretly looking for the most precious thing here. Moonstone is the energy source for the werewolves, so they suspect it's it. It turns out it's not, but they have agitated the werewolves. The werewolves don't like aliens, so they want them out. The aliens have nowhere to hide and they ask the mothership to beam them up, but it accidentally beams up Zed and Addison too. They know what the aliens have been hiding, so they decide to help them. It's revealed that the Scout Commander is Addison's grandma. Addison is part alien. The aliens don't recognize Addison as part of them as she doesn't have spark. Zed wants to help aliens to find the most precious thing, because they might be able to help him get into the college. Zed suggests it could be the Seabrook Cup, so they have to win the competition to get the trophy. Addison wins the competition and get the cup, but the cup is not what they've been looking for. Addison's mom reveals that her hair is white too and Addison's grandma's most precious thing is not a thing but her granddaughter, Addison herself. By scanning Addison, the aliens are able to get a dynamic location of the utopia. However, the mothership is broken, they can't fly it. To make it work again, they need help from others. Zombies, werewolves and cheerleaders take up their parts to help them fix the mothership. As Addison is part alien and part human, she is the literally the connector of both worlds. With everyone's help, the mothership is working again. To get to the utopia, they have to bring Addison with them. Addison has been looking for her people, so she doesn't mind going with them.
It finally comes the graduation. They miss Addison, because they wouldn't even be able to blend in to the community without Addison. Addison helps them fit in in their own way without losing their own qualities.
The reason why Addison has white hair is finally uncovered in the final installment of the series. She is indeed an alien. She has been trying to hide who she is by wearing wig, but she eventually found out she didn't have to pretend someone else. She can be herself by showing her true color. This is just who she is. The world she is living in is not perfect and full of unfairness, so she stands up for them. She wants everyone, including zombies, werewolves and aliens, to be treated equally, because they deserved to be loved as well. Love is so powerful that it can make the world a better place for not only human.
