As always, Sickan has come up with a new plan. This time he wants to rob the IKEA furniture store. During their nightly break-in Sickan discovers that the store is used as a secret smuggling central for sending American computers to the Soviet Union. The computers are picked up by Soviet submarines sneaking into the Swedish archipelago. Naturally, it is their arch enemy Wall-Enberg who is behind all of this.
