A comedy about a Danish private detective, normally just occupied with cases about unfaithful spouses, is suddenly involved in murder, arms deal, revolution in Guateragua, briefcase full of money and the Danish intelligence agency.

This three-part movie begins with a young woman married to an older, cold-hearted man in the year 1200. Two rivals have a swordfight over the affections of the woman. Part two takes place in 1910 and finds an amorously unfaithful wife taking on her many lovers while her unsuspecting husband lurks nearby. The final part finds a count and countess engaging in extramarital affairs in France during the 1840s.
