Set in Argentina in the mid-70s, a stranger arrives in a quiet provincial town. In a restaurant, for no apparent reason, he sets about attacking Claudio, a well-known lawyer. The community supports the lawyer and humiliates the stranger, who is thrown out. Later, on the way home, the man intercepts Claudio and his wife Susana once again, determined to wreak his terrible revenge on Claudio. The lawyer therefore sets out on a road of no-return, of death, secrets and silences.
