Elias, the central character of the film, follows his wife's wishes by seeking out a priest to perform the last rites on their unborn son, whom she fears will die due to a fall she sustained.

Upon finding one, he manages to persuade the priest to return with him to the village to perform the last rites, despite putting the safety of the community at risk.

Rodrigo Plá wrote the screenplay with his wife, commenting on the story and themes as follows: The primary idea is generated from the reading of the philosopher Søren Kierkegaard, particularly where it accounts for daily life.

The completion of the script was a very long process, where it was severely restructured, one to contextualize the story in Mexico, and another to define the structure into chapters.

The Cristiada topic is very interesting and seductive, but that was not our subject, our story was of that family, that guilt, that punishment, that madness.The Cristero War within the film works more as a backdrop to the theme itself.

We knew what we wanted to tell and the characteristics that we overlaid the religious conflict with were ripe to justify certain events which were the substance of our story: the lack of priests in the country and therefore a clear spiritual guide, the prohibition of public worship and the closure of churches, religious exacerbation, all this gave credibility to certain aspects needed in our history.
