During World War II, a young boy and girl, living with their respective families in an apartment house that had restrictions against pets, adopt a lost dog and hide it in a vacant apartment, which may have been the only vacant apartment in the United States at the time this movie was being filmed. A burglar breaks in and the apartment is damaged when the dog and crook have a tussle. This blows the dog's cover, but the kids enlist him in the K-9 Corps, and the dog distinguishes himself in the WWII Italian campaign

The first production from Frontier Films, the film production collective that was the successor to NYKino and the Workers Film and Photo League, Heart of Spain focuses on the Spanish Civil War, a conflict that became a touchstone of its era and was the most forceful opposition to the rising threat of fascism in Europe. Heart of Spain was begun by Geza Karpathi and Herbert Kline, who ultimately turned their footage over to Paul Strand, Leo Hurwitz, and Ben Maddow to make the film. It is compelling both for its shrewd formal aesthetics and as a sympathetic human document of the war.

Cinco fueron escogidos taking place in Slavko, a "peaceful town in Yugoslavia," with only Yugoslavians and Germans as characters, not a Mexican or Spaniard in sight. Another interesting point about Cinco fueron escogidos is the existence of an alternate version, shot in English with a different cast (at least in major roles). Sadly, this film, usually referred to as "Five Were Chosen" but sometimes called "Hostages" (not to be confused with the somewhat similar 1943 Hollywood movie with that title), appears to be lost. García Riera indicates the English-language version was screened in Mexico, at least for the press, but does not seem to have been released commercially in the Mexico or the USA. Since Herbert Kline was well-known for his leftist views, it's not surprising to note that many of the imported Hollywood actors were also left-leaning (and in fact more than one was blacklisted during the Red Scare era).
