When three kids explore Charterville's haunted Hillhurst Mansion on a dare, they discover a lot more than they bargain for! The trio find a wild and wacky phasm named Flabber, who changes their lives forever when he grants their wish to become the superheroes they've read about in BeetleBorgs comics. However, not only does Flabber grant the kids' wish, but he also accidentally facilitates the escape of supervillains from the comic books as well! Now it's up to these three newly tapped superheroes - aided by a friendly neighborhood phasm and armed with fantastic powers and awesome vehicles - to save the world from the forces of darkness that threaten the peace and harmony of all mankind.

Taking its inspiration from season two of the popular live-action Fox series, this movie continues the adventures of a lovable group of teen heroes who have the ability to change into exoskeletal superheroes named BeetleBorgs. They use said powers to defeat evil in all forms.
