A seemingly anti-bourgeois group of adults spend their time seeking their inner idiot to release their inhibitions. They do so by behaving in public as if they were mentally disabled. At a restaurant, the patrons are disturbed by the group's antics, which are barely contained by their supposed “handler,” Susanne Anne Louise Hassing. The group refers to this behavior as spassing, a self-imposed provocation born from a belief that society keeps their intelligence confined and unimaginative.
Karen, a single diner, becomes unintentionally drawn into their act. She first encounters the group with a sense of sympathy, momentarily thinking their pretended disabilities might reflect real struggles. When one member takes her hand, she reluctantly goes along with them into a taxi, only to discover, as the ride unfolds, that the spectacle is a performance rather than a genuine affliction. Upon arriving at a large house, Karen learns that Stoffer Jens Albinus, the apparent leader, isn’t selling the property as he claims; the house becomes the stage for the group’s provocative experiments.
The concept of spassing is presented as a deliberate, self-defeating challenge to “respectable” society. The group members seek a raw, uninhibited form of self-expression they imagine is possible through a romanticized disability, hoping to unsettle the rules of everyday life and draw attention to their frustrations with conventional norms.
During Stoffer’s birthday party, the group pushes further as he wishes for a “gangbang,” a moment that would involve group sex without Karen’s participation. Meanwhile, Josephine [Louise Mieritz] wanders off and is followed by Jeppe [Nikolaj Lie Kaas], and the two share an private, uneasy moment as they connect on a deeper level. The following morning, Josephine’s father [Anders Hove] arrives, scolding the group and chastising Josephine for not taking her medication, demanding she return home. Jeppe makes a desperate attempt to intervene by clinging to the hood of a car, but the effort ends with a tearful exchange between him and Josephine.
As the tension escalates, Stoffer calls on the group to allow idiocy to invade their daily lives. Most members refuse and choose to leave, and the group dissolves. Karen, however, decides to pursue the challenge. She brings Susanne back to her house, where Karen’s mother [Lone Lindorff] greets them with surprise. Karen has been missing for two weeks, following the death of her young baby, offering no explanation. In a startling moment, Karen attempts to spaz in front of her family by dribbling her food, but a violent slap from her husband, Anders [Hans Henrik Clemensen], abruptly ends the scene. Karen and Susanne leave the house together, stepping back into a world where the search for an unguarded self continues to estrange them from the life they once knew.
