Written, directed by and starring Robert Duvall, this thriller romance is set on the streets of Buenos Aires, Argentina. Duvall plays John J, a retired hit man who has settled down to a quiet life in New York with his wife Maggie (Kathy Baker). When he is made an offer he cannot refuse to go and kill an Argentinian General, he sets off for Buenos Aires, only to discover on his arrival that the General has delayed his return. To pass the time, John decides to learn the tango - and before long has fallen passionately in love with his beautiful dance partner, Manuela (Luciana Pedraza, Duvall's real-life girlfriend). Seduced by her rich and sensual world, he starts to lose sight of his real reason for being in Argentina, until his idyll is cruelly shattered and he finds himself caught up in a lethal conspiracy.
