Joan of Arc, a dangerous and efficient combat dog,
has escaped from a military canine division. The one
responsible is Simón, who must bring her back. He arrives
at the remote house where Jean Pierre, a Frenchman
who trains and sells dogs to the army, lives with his family:
Cristal, Albertina and Amado, a motionless and deformed
man. They welcome him with great kindness, and he
quickly discovers that Joan of Arc returned to the house,
but the animal’s obsession with Amado prevents him from
taking her back. The family invites Simón to stay some
days to choose and train another dog that will obey him.
As his stay lengthens, Simón gradually forgets his original
mission. He eventually discovers that the one who truly
dominates the dogs is Amado, who has created a language
of almost imperceptible whistles with which he controls
them. The entire family moves to the rhythm of his desires.
Yet the most surprising thing is not that, but the fact that
Amado wants Simón to turn into his new favourite nurse.
