The Tango Lesson is about a female filmmaker (Potter) who discovers and falls in-love with the tango. In between bouts of writing a screenplay for Hollywood with which she finds herself increasingly dissatisfied she places herself under the tutelage of Pablo, an Argentinean tango dancer living in Paris. As the lessons proceed, they strike a bargain: if he will make her a tango dancer, she will make him a movie star. He accomplishes his side of the bargain when they perform in a show, but her attempt to make a film with Pablo in Buenos Aires exposes the complexities at the heart of the story – how do you follow when your instinct is to lead?
