I just viewed this on IFC channel and definitely recommend to anyone who may want to learn the tango. Besides the (rather predictable) story line it has so many great authentic tango dancers of all ages that for that reason alone it is worth viewing. I found myself getting up to dance repeatedly and I enjoyed the drama as well, though on my part there were no surprises. It was based on political issues in Argentina, so those who have an interest in that will see it, but the main story is of unrequited love on many planes and of passion for the dance (as well as other passions).
The major story revolves around a theater company going into production and a mafia boss who has a "protégé" who he wants to have given an audition. She is ambitious and later rejects him and we expect to see some consequences.
