To shed light on the premature death of her son, Sara, a former internal secret service agent, tired and withdrawn to a prison of solitude, back to asking for a favor from her former friend and colleague, Teresa. But you know, nothing is for nothing. And in an instant, she finds herself entangled in her old life. Whether he wants it or not, it's still the best: the "invisible woman" called her, and her dowry never stopped being requested. So, while discovering the life of her son, of which she ignored almost everything, Sara sinks into an investigation that brings her back to many ghosts of the past. Keeping the two together is very difficult, and certainly very dangerous. Paradoxically, however, this is how the invisible woman returns to live and do what she does best. Justice.
