El décimo infierno (2010)

A city in the Northeast. Alfredo is a friend and partner of Antonio in a real estate business. He is also the lover of Griselda, Antonio's wife. This clandestine relationship has been going on for years until the day when Alfredo, after a furtive encounter, asks Griselda if they should kill Antonio. Griselda simply re-asks how would they do it. As they abandon principles and values, they are absorbed by a maelstrom that apparently has an only exit -death.
