The movie begins with Buldont and Acha scouting the location for his film studio (Buldont Studio) and the film The Century of Baranoia that he is preparing to make. Camera Trick is dispatched to kidnap unwilling participants in the film. After a string of disappearances, Goro (Ohred) and Juri (Ohyellow) are sent to investigate. They discover that Acha is distributing flyers from a plane to recruit cast for the film. They also encounter Camera Trick after it kidnaps a girl reading the flyer. The two give chase, but are intercepted by a malfunctioning Barlo Soldier.
The group of kidnapped kids are greeted by Locker Knight then led into Buldont Studio and shown around the bizarre soundstage where Acha introduces himself as Producer. They are given “Artificial Reality” goggles and are lead on a virtual train ride where they meet with Neko Signal. Goro and Juri meet up with Shohei (Ohgreen), Yuji (Ohblue), and Momo (Ohpink) who are waiting for them just outside of Buldont Studio. They break into the studio in their groups just as the kidnapped kids are lead away on a bus. Once on the soundstage Shohei, Yuji, and Momo are attacked by Kabochumpkin while Goro and Juri fight Neko Signal and Jagchuck. After their brief seperate fights, all three monsters vanish forcing the now rejoined Ohrangers to travel through a mysterious portal to a battlefield.
Once on the field they chase after the runaway bus with the kids, on horseback, after their driver is accidently shot. They manage to save the kids just in time before the bus explodes. They then try to escape, but are trapped on a suspension bridge which predictably breaks, causing the Ohrangers to fall and the kids to get kidnapped by Baranoia once again. The Ohrangers make it back to the battlefield where they discover that the masked grunts that the Barlo Soldiers have been fighting are really kidnapped people. The kidnapped kids are set up for execution but are saved by the Ohrangers just in time. After fighting off the Barlo Soldiers, they stun Locker Knight, Neko Signal, Kabochumpkin, and Jagchuck with a shot from the Big Bang Buster. All four monster combine into the gigantic Steampunk, which once again kidnaps the kids. Ohrangerrobo is summoned and the two begin fighting. Ohred enters Steampunk and retrieves the kids for the final time. Steampunk now transforms into a locomotive form to attempt to evade Ohrangerrobo. Ohrangerrobo does the Crown Final Crash while Steampunk is crossing a bridge which destroys the bridge and causes Steampunk to fall to his explosive death. Buldont, Acha, and Kocha abandon the studio and flee Earth.
The Ohranger Movie is possibly the most crazy bananas Tokusatsu feature ever made. On top of being straight up weird, it is delightfully entertaining. There are plenty of little skirmishes throughout and, despite it’s extended runtime, never a dull moment.
