La Mujer De Mi Hermano ( "My Brother's Wife") could be considered in a category of films that critic Alissa Quart calls 'hyperlink movies', in which multiple stories take place, each affecting the other in ways that characters are unaware of, all the while using radically different aesthetic and cinematic techniques to define the mise en scène of each storyline.

Hoping to find the excitement she craves in forbidden fruit, Zoe falls into an affair with Gonzalo (Manolo Cardona), Ignacio's rough-edged but handsome brother.

During their encounters, she complains to Gonzalo that Ignacio seems uninterested in her sexually as he only makes love to her on Saturdays and rejects her advances regularly.

On the other hand, Ignacio is running the family business and blatantly states that Gonzalo is a good-for-nothing and a moocher as he doesn't work and simply collects his monthly stipend.

Zoe and Gonzalo's passionate affair is satisfying to them both, but the adulterous couple must deal with the sharp sting of betrayal when Ignacio finds out they've been sleeping together.

For this film, director Ricardo de Montreuil and novelist Bayly intended to take the story in a separate and somewhat different direction than the novel.

"When María Eugenia Argomedo and I began collaborating on the script, we were hoping to make something new out of the material, rather than simply reproducing the book onto film," said Montreuil on an IFC interview.
