The kids head to Hollywood to interview Bobby Mogul about his new movie The Amazing Wonder Car, but soon realize that he doesn't like reporters. Before they get there, the stunt guy quits the movie because a Gremlin is out to ruin it, so the gang decides to take the job to get behind the scenes.
Genius director, Bobby Mogul told his stuntman to do his stunt for his awesome film, The Amazing Wonder Car. But when the stuntman started driving his Wonder Car, the engine just exploded. Bobby Mogul noticed a note from a monster called a Gremlin to told Mogul to stop directing the film. Then the stuntman began to quit the film, much to Mogul's dismay.
Meanwhile, the gang is heading towards Hollywood to check on Mogul's film. But when they fall for one of Mogul's stunt, Mogul decided to hire the gang for his movie. The gang realized that Mogul couldn't stand reporters when Mogul showed them a man named Eric, who played the villain in the movie.
The gang was forced to do another one of Mogul's awesome stunts. Then the Gremlin started attacking the film again. So, without Mogul noticing, the gang decided to investigate where the Gremlin could be.
Moments later, the gang started to do the finale while the Gremlin started spilling oil in the streets. Then the gang ran over Mogul's Cybernaut, which was controlled by the Gremlin. When Scooby used oil to stop the Cybernaut, Daphne spotted the Gremlin.
The Gremlin tried to escape but then slipped on the oil he spilled and the Scooby finally caught him. The Gremlin was unmasked as Mogul's script writer, Mickey Hack. He wanted revenge for the changes for his script, which was supposed to be a love story. Eric took Hack to the police when Hack hurt Mogul's feelings.
Mogul wanted them to be in another one of his movies. But Shaggy and Scooby told Mogul that they can't do anymore stunts and leave the exact same way the came.
