A Butterfly in the Night

Yvonne is a Parisian sex worker who catches the eye of Jorge, a wealthy landlord who becomes infatuated with her. He brings her back to his native Argentina, hoping to give her a different life at his estate. Once home, Yvonne faces a clash of worlds, from provincial gossip to the expectations of Jorge's circle. The story follows how she adapts to new surroundings, how relationships with figures like Lorenzo, Vicente, and Pedro complicate matters, and how desire, power, and social class shape each character's choices. The film keeps its focus on personal dynamics rather than plot twists.

Released in 1976, the picture was directed by Armando Bó and stars Isabel Sarli alongside Bó himself, Víctor Bó, Vicente Rubino, and Juan José Miguez. It continues the long creative partnership between Bó and Sarli that defined much of their work in Argentine cinema.

The film did not register as a major international hit and didn't report notable box office milestones, performing modestly in regional markets. Its distribution was primarily aimed at audiences familiar with Bó and Sarli, rather than a wide global release.

Over time the movie has stayed visible among fans of Argentine genre cinema, largely because Isabel Sarli was an iconic screen presence. For viewers who follow the Bó-Sarli collaborations, this film is often cited as characteristic of their approach to sensual melodrama and small-scale production values, and it still turns up in retrospectives of their careers.

Contemporary responses are mixed, reflected in a low average rating from a small number of voters. Critics and viewers tend to note the film's focus on desire, class difference, and the tension between public reputation and private longing. Stylistically it favors intimate scenes and melodramatic beats, which will appeal to those interested in 1970s Argentine cinema but may frustrate viewers seeking tighter plotting or modern pacing.
