Many years after the events of My Little Pony: Friendship Is Magic, Twilight Sparkle's teachings on friendship and harmony have been replaced with paranoia and mistrust, and the three pony kinds – Earth ponies, pegasi and unicorns – live separated from one another. In the Earth pony town of Maretime Bay, Argyle Starshine tells stories of Twilight Sparkle and her friends to his young daughter Sunny Starscout, who inherits his dream of reuniting the three pony kinds.
One day, after Sunny has grown up, a lost unicorn named Izzy Moonbow wanders into Maretime Bay. The town's residents react in panic, believing that Izzy is a hostile invader. Sunny, finally given an opportunity to make friends with a unicorn, shelters Izzy in her home, and Izzy reveals to her that unicorns no longer have magic powers following their sudden disappearance. Together, they embark on an adventure and travel across Equestria on a mission to restore magic to the land.
The movie begins as Sunny is imagining one of Twilight and her friends’ adventures, only for Sprout to intervene. Sunny then asks Argyle if they can leave, in which they proceed to leave. Argyle then plays Unicorn with Sunny, while Sunny is a Pegasus. Then, they send a letter of friendship to the Unicorns and Pegasi. Argyle then tells the story of Twilight again. Afterwards, Sunny goes to bed.
A few years afterwards, now grown-up Sunny starts her day by roller skating into town with her smoothie cart. Then, she tries to enter the Canterlogic factory, but Hitch stops her. Then, Sunny goes inside after telling she won’t scare anyone. Inside of the factory, Phyllis presents new gadgets to help the earth ponies. Then, she presents one last thing, and Sunny jumps up, saying that fear is not their friend. This results in Sunny being apart of the gadget. She tries to convince the fillies the exact same thing, but Phyllis doesn’t want her to.
Hitch then tells Sunny how many laws she broke and walks away sad. Then, a unicorn named Izzy comes into Maretime Bay, scaring all of the residents, and then a trap comes up as Hitch and Sprout are trying to capture her. Every attempt failed, but when Sunny and Izzy got to the movie theater, the trap caught Izzy, but Sunny released her. Sunny and Izzy runs to Sunny's lighthouse for shelter.
