La Mary is a 1974 Argentine romantic-drama film directed by Daniel Tinayre starring Susana Giménez and Carlos Monzón.

The film is set in the 1940s and centers on Mary (Giménez), a young girl from a working-class neighbourhood in Buenos Aires who has the reputation of being able to predict the future.

La Mary was a box office success and generated controversy due to its topic, so much that the Triple A threatened to kill the entire cast, accusing them of "offense against morality and decency.

[1] In 2014, for the 40 year anniversary of its release, the film was remastered and re-released, declared "of cultural interest" by the city of Buenos Aires and the subject of an exhibition at the Pablo C. Ducrós Hicken Museum of Cinema.

[1][3] By 1930, Evaristo, a humble worker who lives near the Riachuelo river in Buenos Aires, is preparing to go to work with two partners.

During the wedding party, Tito, a pharmacist friend, reveals to Mary that Rosita is marrying because she is pregnant and an abortion was too dangerous.

At hearing the word "abortion," Mary feels revolted, gets dizzy, and flees the party.

That summer, Mary is reunited with the man from the bus, Cholo, who works for a meat packing company with his brothers and is also a boxer.

The previous delivery had complications, and Sofia fears what will happen if she decides to continue with the pregnancy.

Mary's "prophecies" continues to be fulfilled: After Ariel dies, Claudia finds a boyfriend and plans to remarry.

When Cholo is asleep, Mary gets up, strips herself naked, puts on her wedding dress, and takes a knife.
