A group of actors—Left Bank students, artists, and exiles—is haunted by a vague, unseen menace, some kind of worldwide conspiracy. “This note of Fritz Lang paranoia abroad in a vividly realized Paris is but one fascinating element in the dynamics of Jacques Rivette’s maiden feature, a precursor of his great films about acting troupes and amateur detectives pursuing Truth through the rehearsal of fictions” (American Cinematheque). The experimental score is by Philippe Arthuys, a member of Pierre Schaeffer’s Groupe de Recherche Musicales, and the plot centers on the quest for a lost cassette tape of modernist guitar music.
