Karl, two years old, is discovering the world, and his father does not want to stand in his way. Karl's expeditions into the world of objects in their home and on the street, at the playground and in shops, which his father lovingly accompanies, evoke numerous memories and reflections about his own childhood and its world of objects. The father wants not only to preserve Karl's childhood happiness but also to save and cherish the things from his own childhood. This is not the only conflict in his close relationship with Karl's mother, Klara, who works at the heritage conservation office and sends instructions for Karl's upbringing via text message from the office. Additionally, the prospect of finally moving into a shared apartment threatens the treasure trove of meaningful everyday objects that the narrator keeps at home. A treasure trove of observations and reflections, treacherous.
