Also Directed by Carlos Durán
A drug has been discovered, Liberxina 90, which will erase "establishment" conditioning from the human mind. It has fallen into the hands of some diversely anarchistic revolutionaries who spend most of the film discussing how and whether to use it; should they wait for the forces of "history" to undermine society or speed things up using the drug? They are finally forced into action by the police who are, somewhat ineptly, hunting them down.
Along with narrating the adventures and misadventures of its protagonists, the film presents a fresco of Spain in the 60s, with its rock music, fashion, and a visual style clearly indebted to the French New Wave.
The intrusion into the private life of a human being, of the distinct tendencies that exist in the society we live in, until they fall into chaos. –Carlos Durán
