Jönssonligan dyker upp igen (1986)

The Jönsson Gang—Charles-Ingvar “Sickan” Jönsson, Ragnar Vanheden and Dynamite-Harry—pulls off a clever plan to rob the cash vault at Ikea, but the alarm goes off at the final moment and they fail to get away with the money. On the other hand, Sickan discovers that a gang is using returned Ikea furniture to smuggle American military equipment to the Soviet Union. During its brief stay in Sweden, the equipment is kept in the so-called armored room at director Wall-Enberg’s headquarters and guarded around the clock by his henchmen. If the Jönsson Gang can steal the equipment from the armored room, they can then blackmail Wall-Enberg for money. A Soviet submarine is supposed to secretly pick up the stolen equipment, but when they arrive at the rendezvous, the Jönsson Gang, the police and Wall-Enberg’s gang are all there. Sickan and his accomplices manage to trick their rivals out of the equipment by disguising an ordinary rowboat as a submarine’s conning tower, while Vanheden swims ashore in a diving suit. They deliver the equipment afterward, but unfortunately are paid in rubles printed before the revolution. Meanwhile, Doris has bought a sofa from Ikea’s bargain corner. When she later meets up with the gang on a ferry to Finland, it turns out that one of the cushions is stuffed with the money from the Ikea heist.
