I gave "Perdóname Señor" a probably too generous 6 out of 10 based on the strong performances of a number of cast members, in particular Paz Vega, who plays the lead. Otherwise, the story drags a bit and comes to a far too predictable end.
The mini-series begins with Sor Lucía on the beach of her hometown, having just returned after many years in Rome, getting a bit of seaside relaxation in before starting a teaching assignment in the local high school. She is dismayed to see not just a big delivery of hashish arriving by boat but that her nephew is one of the hired hands participating in the shipment. While Sor Lucía is trying to wrest a bundle of hash from her nephew, the police arrive & arrest her. Yeah, a nun arrested for narco-trafficking, a bit awkward. She learns that her nephew is aspiring to the big time in the drug world because he sees it as his way out of this dead end small town. And the kingpin who the nephew is trying to topple is none other than her old high school flame. Plot lines are not this mini-series' forté.
Yet the strength of the cast makes "Perdóname Señor" watchable, well, almost. I found myself watching one episode after another just to find out what happens, only to roll my eyes at an ending you could figure out from a mile away. Oh well, did I mention the actors were pretty good?
