A wild herd of unicorns attacks an island village while a cameraman catches the attack on film. He knows that he will die, but he hopes that his footage will make it back to the Mainland so that people will know how dangerous unicorns really are.

It is the morning of the Chaos Cup, the biggest unicorn race of the year. Skander, his dad, and his sister Kenna all wake up excited for the big race. However, Kenna’s mood fades when she remembers that she failed the Hatchery exam and lost her chance to be a unicorn rider. While Kenna gets ready for the day, Skander and his dad talk about the race prospects, Skander’s dream of becoming a unicorn rider, and Skander’s friends—of whom he has few because he must regularly take care of his father.

The race begins, and Skander’s favorites—Aspen and her unicorn, New-Age Frost—start at the middle of the pack but quickly take the lead through displays of elemental magic. They win the race, but their victory is short-lived when the Weaver, a rider clad in all black except for their white mask, rides in on a wild unicorn and steals New-Age Frost.
