[1] The story, depicted cinematically through a series of poignant still shots and accompanied by off-screen dialogues, unfolds over the course of a single day, June 14, 1935.

Their son, Maximiliano Ramón Caballero, had departed to join the Chaco War, and both parents anxiously await his return.

The father holds onto hope, confident in his belief that he will reunite with his son alive, while the mother is burdened by the darkest of forebodings.

Both stand vigil beneath an overcast sky that threatens rain but never delivers, enduring unrelenting heat, unmitigated by even the slightest breeze.

The constant, irritating barking of the dog their son entrusted to their care during his absence adds to the tension.
