Taking it's title (as a reference, or homage) from Alain Resnais' pivotal 1956 documentary Night and Fog, the film has a group of former student revolutionaries who meet again years later at the wedding of one of their classmates. Old feelings, rivalaries and grudges gradually erupt to the surface as the one-time friends recall the various treacheries by which their cause was defeated. Cutting between times pas and the present and unfolding the action from each of his characters viewpoints, Oshima creates an abstract and yet engrossing study of passions past and principles eroded.
