Released in 2018, the film is a cinematic adaptation of the mystery novel titled "Las Grietas de Jara," written by captivating Argentine author Claudia Piñeiro. The film was produced by Axel Kuschevatzky, Juan Pablo Galli, and Juan Vera.

The storyline of Las Grietas de Jara unwinds the mysterious world of renowned architect Pablo Simó, played by Joaquín Furriel.

The opening scene presents the protagonist, Pablo Simó, living a seemingly ordinary life. He holds a steady career in an architectural firm, has a beautiful family, and is an apparent pillar of success. However, life holds its surprises when into his rather sophisticated corporate milieu enters an uncannily curious and persistent woman. Laura Lima, played by Clara Lago, brings with her a storm of change by requesting information about Nelson Jara, performed by the incomparable Oscar Martínez.

Nelson Jara, the character invoked by Laura, had previously been a client of Pablo’s firm and had gone missing, setting the plot's intrigue. Pablo’s unnerving familiarity with Nelson’s odd disappearance, coupled with Laura’s determined probing, sets in motion a whirlwind of investigations and discoveries.

This suspenseful narrative aptly features associations linking Pablo's architectural career to the mystery surrounding Nelson’s disappearance. The title, "Las Grietas de Jara" or "Dark Buildings," metaphorically portrays the movie’s connective thread, reflecting the cracks in the structures Pablo designs that parallel the glitches in his personal and professional life. The brilliantly captured architecture within the film also plays an allegorical role, drawing symbolic parallels between the faults in structural designs and the flawed human nature, further enhancing the film’s dramatic intensity.
