Scooby-Doo! Stage Fright

The Mystery Gang travels to Chicago to attend Talent Star, a high-profile talent show hosted by Brick Pimiento at the opera house. Fred and Daphne are among the finalists with high hopes, and Shaggy and Scooby plan to showcase a juggling act to boost their chances.

Chrissy Damon is a spoiled finalist whose loud parents make her hard to root for, while Emma Gale is a kind violinist who befriends the gang. Fred and Daphne also meet Mel Richmond, the opera house owner, and the Phantom looms around the venue.

The Phantom makes his first appearance inside the opera house, and Fred, Daphne, and Velma scramble to catch him using surveillance cameras. The Phantom’s ability to appear in multiple places at once foils their plan, forcing the group to split up. Shaggy and Scooby catch a whiff of a lemon scent during a brief chase, adding a clue.

Dress rehearsals begin and the Phantom sabotages most acts, leaving Chrissy, Emma, and Fred/Daphne as the remaining contestants. The sabotage escalates, prompting the gang to decide to use themselves as bait to lure out the Phantom and expose his identity.

Fred and Daphne volunteer as bait, drawing the Phantom out and letting the gang close in. They manage to corner a Phantom only to discover the original Phantom is Steve Trilby. Steve admits vandalism stemmed from his disco hatred, revealing a personal motive.

With Steve’s help, the gang confronts the Phantom as the opera house catches fire. Steve explains his part in past vandalism and the team braces for a showdown with the current menace. They realize the person they’re chasing may not be the true Phantom.

The Phantom is revealed to be Mel Richmond, the opera house owner, who hoped to destroy the venue for insurance money. Steve aids the gang in capturing this Phantom and putting a stop to the current threat.

But a new twist surfaces when they learn the real Phantom threatens to destroy the opera house unless Chrissy wins, escalating the stakes for the talent show. The Phantom’s demands push the finale toward a chaotic finish.

That night, Emma is used as bait and the gang captures the Phantom, who turns out to be Lance Damon, Chrissy’s father, wearing a girdle. The revelation adds a personal motive to the sabotage and deepens the mystery.

Shaggy and Scooby uncover that assistant director Dewey Ottoman is also the Phantom, after spotting lemon-scent sanitizer in his office. They realize Ottoman orchestrated the police patrols to leave the mineralogical center unguarded. The team heads to the mineralogical center to confront him.

Ottoman attempts to flee with the Soap Diamond, triggering a chase that ends at the mineralogical center. Scooby catches the diamond after Ottoman drops it, and the criminals head toward a drawbridge. Fred devises a plan to thwart Ottoman by luring him into a garbage barge.

Ottoman trips and drops the Soap Diamond; Scooby catches it. A dramatic drawbridge chase ensues, and Fred tricks Ottoman into jumping into a garbage barge. The gang returns to the opera house just in time for Fred and Daphne's tie-breaking performance.

Velma reveals that Brick Pimiento wore the Phantom costume to boost ratings, exposing him as the mastermind behind the scheme. Pimiento is arrested as the truth comes to light and the finale proceeds.

Steve wraps up the Talent Star finale, and the network announces that he will be the new host for Season 10. The gang watches the crowd and reflects on the night’s events, curious about what comes next.

Velma hints that Daphne should talk to Fred about their relationship, while Shaggy and Scooby urge Fred to do the same. The group then heads toward Goose Lake to solve the Goose Lake Monster.
