[1] After a tremendously daring or at least badly planned and utterly unsuccessful attempt to rob a savings bank, Egon is jailed.

Despite Benny and Kjelds objections Egon is clear in his mind, and instead they also begin a life of being lawful citizens.

Although it starts well for the gang, they are eventually thrown back towards a criminal path, when they are accused of a robbery committed right in front of them in the vault of the Danish National Bank, where they serve as cleaning people, after a mishap at the toy factory.

Although the police think that the gang committed the robbery, it is in fact the mafia boss Serafimo "Spats" Motzarella [sic] (Harold Stone) who sent a team to rob the vault and place the loot, allegedly the Danish crown jewels, in a cello case.

After a long car chase and a lucky escape, they enroll Benny's heavily alcohol-using brother Dynamite-Harry, an expert in explosives, to open cello case at a remote gravel pit.
