Phantom of the Megaplex

17-year-old Pete Riley works as the assistant manager at the local 26-screen grand megaplex, a job that he loves and spends the majority of his time at. Rumor has it that the megaplex is haunted by a "phantom", someone who was trapped inside the old movie theater that was demolished to build the current megaplex. Pete, senior manager Shawn MacGibbon, the other employees, and an elderly member of the family who once owned the original theater known as "Movie Mason" (played by Mickey Rooney) who loves movies and thinks he works at the megaplex, are working to prepare the theater for the star-studded premiere of the new Hollywood blockbuster Midnight Mayhem. Wolfgang Nedermayer, the owner of the megaplex, is to be among the guests. To Pete's disappointment, he is forced to bring along his younger siblings, 11-year-old Karen and 10-year-old Brian, to the theater while their widowed mother goes out on a date with her boyfriend George.

Pete dumps his siblings in a movie (which Karen ditches to see a horror movie with her friends) so he can focus on setting up for the premiere, but problems begin to pop up all through the megaplex. The other movies begin to suffer mishaps, which Karen and Brian realize are all related to the titles of the films being shown (for example, a theater showing a movie called Cyclone Summer has a giant fan moved in front of the screen, which blows everyone out of their seats). Pete, Karen, and Brian work together and discover that the rumored phantom is behind these acts of sabotage. Through online spoilers, Brian and Karen are able to learn the movie's plot, and Pete is able to stop the phantom from sabotaging the premiere. The phantom is revealed to be Shawn, who Nedermayer immediately fires and permanently bans; however, Shawn explodes with anger as he did all this so Nedermayer would finally notice him (and get his name right, since he never did). Shawn is then offered partnership by the director of Midnight Mayhem to make a movie based on his exploits—Phantom of the Megaplex: The Shawn McGibbon Story.

Nedermayer offers Pete the job of senior manager at the megaplex, something Pete has always wanted. Though Pete tells Nedermayer that he'd be honored, he turns down the job. Inspired by Karen and Brian from their help exposing Shawn as the phantom, Pete realizes the importance of his childhood and doesn't want to waste it anymore, asking for the rest of the night off; Nedermayer complies, giving Pete money to treat his girlfriend Caitlin Kerrigan to a nice breakfast after the film. George proposes to Julie, as per suggested by Brian who said a 4–star ending was needed to wrap things up. As everyone enters the movie theater, Movie Mason explains to Brian that he never once believed in the Phantom of the Megaplex; however, "the Werewolf of the Megaplex is another story." Both enter the theater as an employee, "Scary Terri" (known for her horrifying stories), closes the doors as a wolf howl sounds.
