[3] Agustín (Viggo Mortensen) is a man desperate to abandon what has gradually become a frustrating existence after living for years in Buenos Aires.

After his twin brother Pedro's death (Viggo Mortensen), Agustín sets out to begin a new life assuming Pedro's identity and returning to the mysterious Paraná Delta region, which was the childhood home of both brothers.

However, shortly after his return, Agustín is involuntarily involved in the dangerous criminal world that his brother had been part of.

Manuel Piñón of Cinemanía rated the "surprising" noir film 4 out of 5 stars, considering that it is "written with astounding smarts and accuracy".

[4] Rob Nelson of Variety considered that the "tepid" Spanish-language drama is undermined by its "slow pacing, thinly drawn characters, a limp climax and humorless tone".
