Drei Herren (1998)

Dölken, Ivo and Sichel, three amiable and harmless inmates of a mental asylum are off to spend the summer in an open institution in the country. The trip they have been looking forward to for so long ends abruptly when the driver of their bus suffers a heart attack. The three men quite naturally assume that they have reached their destination and find somewhere to stay in the nearest village.
