On a breathtaking tropical island filled with lush jungles, roaring waterfalls, and towering golden mountains, the world-famous Mad Riders Challenge invites the greatest ATV and motocross racers to compete in the ultimate off-road tournament. Young motocross champion Jax Ryder (Javon Walton) leads a talented team of six racers—Mia Cruz, Leo Walker, Riley Stone, Nova Hart, and Chase Bennett—through a series of increasingly dangerous races across the island's unforgiving terrain. From muddy jungle trails and cliffside canyons to massive mountain jumps, every stage pushes their skills, courage, and teamwork to the limit. As the competition intensifies, the racers discover that the challenge is about more than winning trophies. Hidden deep within the island is a long-buried secret that attracts ruthless competitors willing to sabotage the event to claim victory at any cost. With guidance from tournament coordinator Sofia Vega (Selena Gomez), vehicle engineer Dr. Olivia Chen (Brenda Song), veteran champion Rex Hunter (Pete Ploszek), and local explorer Ava Reyes (Louriza Tronco), the team must rely on trust, determination, and friendship to survive the island's toughest courses. Standing in their way is elite rival Scarlett Steele (Alexa Bliss), one of the most accomplished racers in Mad Riders history. While she begins as Jax's fiercest opponent, the growing danger forces both rivals to decide whether winning is worth risking everyone's lives. With engines roaring, dust flying, and gravity-defying jumps across one of the most spectacular racing landscapes ever seen, the Mad Riders Challenge becomes the race of a lifetime.
