A middle-aged birthday party host unwisely soldiers on after a fireworks accident. A teacher sees her colleague transgressing and dares to mention it in the staff room. A coach stops in the middle of nowhere after some passenger infraction. The drunken horseplay of teenage girls goes too far. What can it all mean? Involuntary cuts between a series of discrete micro-dramas, in five parallel stories with human group behavior as the common theme and whose only apparent connection is the film’s title. Presumably, we’re being asked to assess just what it is that motivates these shambling individuals.
