Plot
Following the Olsen Gang's only successful robbery in the previous film, they are seemingly living the perfect life in the basking sun on Mallorca. But they are not happy. Kjeld is homesick, Yvonne has turned into an alcoholic, and money-wasting Benny is in conflict with Egon who has the red suitcase containing their money always chained to his wrist. Meanwhile, the enforcer Bøffen has tracked them down, and he manages to steal the case. Egon is arrested by the Spanish police as the gang try to retrieve it.
Back in Denmark, after Egon is released from prison, he's got a new plan, as usual. So has Yvonne, however: She has alerted the police about the money which were stolen from them in Spain, and she asks for an advance in return. Egon has memorised the complete Danish train schedules as the money has now been invested in gold bars, which are to be shipped to Zürich by train - in an armored Franz Jäger wagon. The gang steal a small shunting locomotive, hijack the wagon and transfer the gold onto a battered medium truck, which collapses under the load.
The gang has to abandon the gold to escape the police, split up in disagreement, but regroup with a new plan after Benny and Kjeld rescue Egon from "disappearing and staying lost". In the meantime the Danish State Railways has switched to the summer schedule, turning the plan into a lethal task. In addition the police have arranged a summer outing via rail and by chance, Bøffen spots the gang towing the wagon along the Copenhagen harbour railway and a car/train chase along Amagerbanen ensures. Luckily Yvonne has supplied the police with what turns out to be a decisive description of both the perpetrator and the armored wagon and eventually the gang is successful in repossessing the gold and launder it through a Norwegian oil company to acquire the majority stake in the shipping company I.C. Lauritzen, making Egon chairman of the board. The tax administration do not see the income from Egon's trade appearing in the accounts, and so he ends up behind bars again.
