Infinity Train will make one final stop at HBO Max on April 15. Ahead of its fourth and final season, Polygon has an exclusive look at the key art and the arc’s full synopsis. The trailer for the upcoming season revealed that it would focus on two characters with a tense, pre-existing relationship, but the new synopsis reveals more details about the characters and their current situation.
The official synopsis is as follows:
Min-Gi and Ryan are childhood best friends who dream of performing in a band and traveling across Canada, together. After a sudden falling out splits them apart, both find themselves aboard the mysterious Infinity Train. Lost and confused, they meet Kez, a free-spirited concierge bell, who accompanies them on their journey. As tensions rise and old wounds come to light, both Min-Gi and Ryan must decide if they can work together or else risk losing themselves forever aboard the Infinity Train.
Created by Owen Dennis, Infinity Train debuted on Cartoon Network in August 2019. Each season has followed a different set of characters as they explore the endless train. The first two seasons aired on Cartoon Network, with the third landing on HBO Max.
