Detective Patricia travels to Matanzas, her hometown, to inform her family after finding out about Mariano's death, who was unjustly accused for sexual abuse.
Determined to find the truth, she will encounter distractions in a town where no one seems to believe her theory that Mariano is innocent, an affair with her ex-partner Ubaldo which appears to raise scepticism about her skill as Detective, but despite the resistance of going against the grain, she ignores everyone who tries to dissuade her for being wrong and persevere over every obstacle put in her way until she finds the real culprit and proves Mariano's innocence.
