Thesis on a Homicide

“Details. The key is hidden in the details.”

A young woman is found brutally murdered, and Roberto Bermúdez (Ricardo Darín), a law professor, becomes convinced that Gonzalo Ruiz Cordera (Alberto Ammann), one of his best students, is the killer. Hernán Goldfrid, working from Diego Paszkowski's novel, follows Roberto as he starts his own investigation. Underneath it is the question of whether a mind trained to build airtight arguments can mistake a theory for the truth.
