The story depicts an Argentinean family which was divided during WWI and ended up fighting on opposite sides. It stars actor Rudoph Valentino in the role of Julio Desnoyers, grandson of Argentine landowner Madariaga.
The movie is famous for a scene involving tango dancing. It occurs in a club of La Boca where Julio goes to enjoy an evening with his grand father. He notices a couple on the dance floor, walks up to them pretending to get the woman for himself, knocks out his rival and conquers her while dancing a very particular sort of tango in his gaucho attire. After looking down on him and laughing in his face, the woman fall head over heels, kisses him on the lips in front of everyone and ends up sitting on his lap at his table.
“The Four Horsemen of the Apocalypse” became the the top-grossing film of 1921, beating Charlie Chaplin and turning Rudolph Valentino into a superstar. The latin lover’s effect was such that men were seen wearing gel in their hair and people began learning to dance the tango.  Another silent movie involving tango dancing and gauchos in the Andes was released in Hollywood in 1928.  Tango remained a recurrent theme in american films ever since, unfortunately perpetuating fantasists clichés for the most part.
