After solving their last mystery at Spooky Island, the Mystery Inc. gang is back in Coolsville, where they are being honored with their very own exhibit at the Coolsonian Criminology Museum. However, when a masked villain steals costumes of classic monsters on display and brings them to life, the gang must come out of retirement to solve the case.

The owner of a bank (Miss Bitterman) wants to own the Muppet Theatre so she can build a nightclub over it. After she tricks Pepe into giving her the only copy of the contract between her father and the Muppets, she changes it so the Muppets have very little time to pay a debt they owe. Meanwhile, the Muppets are trying to put on a Christmas show. After the Muppets are confronted by Bitterman, they make a lot of sacrifices to save up so they can keep the Theatre.
