A young millionairess and flirt (Paulina Singerman) is conquered by a truck driver (Fernando Borel) who gives her a ride when she is on the run from her commitment to an Italian count (Enrique Serrano). The film contrasts the spoiled protagonist who uses the foreign name "Betty" and has never tried Mate tea, the drink of all Argentines, to the hard working, long-suffering poor. The romance almost founders when the truck driver resists joining the cosmopolitan life of the Buenos Aires elite, but is saved when Betty agrees to join him in his more "authentic" world.

The critic "Calki" called the film an agile and well-made comedy and praised the performance of Paulina Singerman and Fernando Borel. He said it had good dialog that entertains and amuses without any pause in the action. The critic Rodrigo Tarruell wrote that "the encounter of Paulina with the truck driver achieved an exalted mix of sexual passion and class struggle worthy of D. H. Lawrence."
