In this surreal (and little seen) Argentinean film, a rich upper class family's secrets are exposed during the course of an evening meal. Tensions mount as emotions run high and taboo subjects are explored such as incest and politics. As their dinner table conversation begins to escalate into physical and verbal altercations, the family awaits the arrival of a friend named Hallewyn. When the night is over, will their friend still be joining them?

A comic strip detective and a superhero are hired to investigate separatedly the successive murders of CEOs within a real life corporation symbolizing a nation, while subversive groups and members of the establishment lead a war for power.

The film tells how in 1970 a group of Argentine filmmakers - including Alberto Fischerman, Rafael Filippelli, Julio Ludueña, Miguel Bejo, Jorge Cedrón, Dody Scheuer and Luis Zanger - decided to make a short film each in one night. The occasion is perfect to describe the atmosphere of the '70s, the fever in which militants and publicists lived, the clash between art and politics. Includes fragments of the films The Players vs. Ángeles Caídos (Fischerman, 1969), Shadows (John Cassavetes, 1959), Made in U.S.A. (Jean-Luc Godard, 1966), L'eclisse (Michelangelo Antonioni, 1962), The Hour of the Furnaces (Pino Solanas & Octavio Getino, 1968), Tire dié (Fernando Birri, 1960), Alianza para el progreso (Ludueña, 1971), La civilización está haciendo masa y no deja oír (Ludueña, 1974) and La pieza de Franz (Fischerman, 1974).
