Touma, Yuri and Mei somehow ended up in the World of Zenkaiger while four Zenkaigers, except Juran, ended up in the World of Saber. The reason for their swap is due to a man who wishes to rid the world of heroes. How does a teenage boy manga artist tie into this? And why are they sent into different stories filled with previous Kamen Riders and Super Sentai Teams?
The 2021 Super Sentai, Kikai Sentai Zenkaiger, debuts in a movie! Previous generations of monsters show up but team leader Zenkaiser won't let them have their way!

With the power of the Machine World, he'll defeat them at Full-Force Full-Throttle!
