American private eye Lemmy Caution (Eddie Constantine) is sent to the city of Alphaville (a futuristic Paris) on a search for a missing agent. There, he struggles with the perils of a techno-conformist society run by the evil Professor Von Braun and his Alpha 60 computer system. With love and self-expression outlawed in the city, Caution naturally enlists the help of the prettiest and most dangerous girl in town: the professor's own daughter, Natacha (Anna Karina). From French New Wave master Jean-Luc Godard, Alphaville is an unconventional, tongue-in-cheek meditation on the impact of technology on society.
