- Plot: A masterpiece of militant cinema of 1968, filmed on the actual barricades of Adachi's very own Nihon University during the period of social struggles. The film begins in a lengthy free-love session taking the form of a 'play' rape being enacted by a group of aimless, listless and political apathetic students. However, when one of the boys falls in love with the raped girl, she asks him to participate in an "experiment" to find out the true meaning of radicalism.
