Voir sur FrenchStream. Egon and the gang are hired to stage a robbery of an antique Chinese vase for an economically challenged baron. Naturally they fooled, which infuriates Egon. The gang tries to get back at the baron by switching the vase with a cheap Hong Kong copy. One attempt is made during the barons hunting party, where Egon ends up being bricked up in the catacombs. In another attempt, the gang has to coordinate breaking through several walls at The Royal Theater in Copenhagen with the "Elverhøj" overture.
