Jorge Villafañez is a rotund, veteran private detective living alone in a high-rise apartment in Buenos Aires. Discreet and meticulous, he has a knack of making people open up in conversations. But when a new assignment puts him on the trail of Elvira, an experimental choreographer, the distance between the observer and the observed begins to collapse as Jorge descends into the rising waters of the Delta del Río de la Plata.

It is set in a women’s prison and follows two of “El Marginal’s” most talked-about characters in the original: the unscrupulous Gladys “La Borges” Guerra (played by Ana Garibaldi) and the cynical Sergio Antín (Gerardo Romano).
