Swedish adventure comedy based on Jonas Jonasson's bestselling novel. Despite having reached his 100th birthday, Allan Karlsson (Robert Gustafsson) still has a sharp mind. Keen to avoid the party that his retirement home have organised for him, Allan climbs out of his bedroom window and begins an escapade featuring criminals and a stash of drug money. Allan, however, is not new to adventure - during his lifetime he was involved with many significant events which changed the course of history and became associated with world leaders and other notable figures along the way.
