In a vibrant, snow-dusted Victorian town brimming with wonder, Jeronicus Jangle, a once-celebrated inventor played by Forest Whitaker, has lost his creative spark and closed the doors to his magical toy shop. His world is turned upside down with the arrival of his bright, mathematically gifted granddaughter, Journey, portrayed by Madalen Mills, who believes in his genius even when he does not. Their joyous reunion is shadowed by a lingering threat: Jeronicus’s former apprentice, the devious Gustafson, brought to life with slick charm by Keegan-Michael Key, who long ago stole his mentor’s most magnificent creation—a sentient, clockwork matador—and has built a fraudulent empire upon the theft. This holiday musical adventure, bursting with original songs and dazzling spectacle, follows Journey as she helps her grandfather rediscover his joy and ingenuity, embarking on a quest to reclaim his lost legacy, mend their family, and prove that the greatest invention of all is belief itself.
