Centenarian escapes care home, steals gang cash
On his hundredth birthday Allan Karlsson climbs out of his care-home window in Malmköping rather than attend his party, and at a bus station he takes a suitcase left in his care by a young gang member; it turns out to hold fifty million kronor. The theft sets off a chase across Sweden in which pursuers die by accident while Allan and a growing band of misfits drift along. Flashbacks show the same man, an explosives expert with no politics, turning up at the Spanish Civil War, the Manhattan Project, Stalin's gulag and Mao's China.
