Sonia is a former militant of the Montoneros. In the 1970s she was a militant in the JP in the western suburbs of Greater Buenos Aires. She begins her journey to the West, to the past, searching and wondering what remains of that revolutionary practice in the very territory where it was tried and failed. But his initial intention fails and he finds, instead, other things: an unexpected balance and demand from the children of that unbeatable generation; the discovery that in the West there were almost no survivors left, due to a particular form of repression; and the most important thing: he discovers his profound need for reflection in order to bring to an end the most intense and tragic stage of his life.
