The first of 14 Olsen Gang films presents us with Egon Olsen, head of the gang, and his friends Benny and Kjeld, who want to become the best known gang in Denmark and eventually Europe by stealing a famous Bavarian work of art currently displayed in a Copenhagen museum. Although Egon's plan works out fine, there is only trouble ahead for the little gang.
