Unlike most other Olsen Gang films, this heist takes place in Jutland.

Egon has obtained a map for a treasure stored in an old German command bunker on the west coast.

To get to Jutland they must cross the then newly built Little Belt Bridge, but two other criminals (Helle Virkner and Willy Rathnov) have also got wind of the story.

They mistakenly believe that it will be easy to fool the locals - they misjudge the wily scrap dealer (Karl Stegger) and his mute assistant (Preben Kaas).

A bomb left over from the war gives Kjeld a short, but very significant, shell shock, which causes him to stylishly carry out a terrific ride in a runaway dump.
