Cheech & Chong are invited to a celebrity party in Amsterdam. When they get there, however, it turns out that the guy who invited them has taken off with all the money. They are actually expecting Burt Reynolds and Dolly Parton, so our heroes get to be Mr. Burt and Mr. Dolly.

Detectives Grijpstra and De Gier are sent to investigate the case of a man who apparently hanged himself in a center for oriental meditation. It is ruled as suicide and the case seems to be closed, but the same night there is an attempted break in. The investigation hits a dead end and everyone involved is a suspect. Based on the book "The Corpse in the Haarlemmer Houttuinen” by Jan-Willem van de Wetering.
