Sure, here it is!
The Mystery Inc. gang arrives at an exciting theater festival in an old and charming town, where they are about to bring to life a famous play called "Romeo and Juliet." But not everything is as it seems, as they quickly become embroiled in a chilling mystery: a terrifying ghost known as the "Phantom of the Opera" begins to haunt the actors, scaring them and causing chaos on stage. This ghost has a tragic past and seeks revenge, threatening to ruin the show and perhaps take someone along in the process.
