The Olsen Gang from Würchwitz want to uncover a secret that has kept researchers, treasure hunters and soldiers of fortune in suspense since the end of the Second World War. With space technology, an unbridled thirst for action and an ingenious plan, the three small-time crooks now want to finally capture their first million. On land, in the air and deep inside the earth, Egon, Benny and Kjeld set off in search of the legendary Amber Room. The Olsen Gang films are cult in the East. In the Würchwitz film studio, the smallest Olsen Gang studio in the world, the legendary films are being remade. In the third part, "The Search for the Amber Room", the Würchwitz film studio receives prominent support: cosmonaut Sigmund Jähn explains his multispectral camera.
