Plot Summary

When Sara takes Beethoven to spend summer vacation with wacky Uncle Freddie in an old mining town, the mischievous canine "digs up" the missing clue to a legendary hidden fortune of Rita and Moe Selig. Now everybody wants to be the dog's best friend as his discovery unleashes a frenzy of treasure hunting among the community's cast of kooky creatures.
