A prim left-leaning doctor goes to work with the community in "Tierra Caliente," a region that spans parts of Guerrero and Michoacan and known for being rather underdeveloped when compared to the major Mexican cities.
Several tropes which were standard for Mexican movies of the time come up (Río Escondido will immediately come to mind). Our urban professional feels an aversion to the superstitious ways of the natives and wants to change them. On the other side of the battle, those who serve to benefit from the status quo (local strongmen, witch doctors, and the people themselves who fear change) overpower him and he makes very little leeway. It's cliché, but the melodrama of a negative cliché seems to be more satisfying than that of saccharine ones.
The movie's plot is further made more interesting because of its duality. Perhaps because two of the biggest names of the Golden Age of Cinema were acting in it (Arturo de Cordova and Pedro Armendariz), the two plots that each of these characters pilots seem to be so distinct that it feels as if I watched two different movies. The romance-drama of the middle-aged doctor falling in love is the main focus for a while but then the movie shifts to an action-drama about Roque's (Armendariz') shenanigans, with a significant shift in tone along with it.
People familiar with the culture of Tierra Caliente will no doubt be pleased with the more or less accurate portrayal of the people from this region in terms of dialect, costume, and culture - they really did their research for this one.
One important thing to mention is that the movie basically justifies a rape and ends up exonerating the perpetrator in the plot by his subsequent behavior. The blasé attitude toward this whole issue reminded me of Bad Timing (1980).
It was an effectively sad movie. The ending speech was strong, but it seemed a little misplaced. In the same hodgepodge manner as the film as a whole, it focused on a specific aspect of a story which had too much diversity of plot and moral dilemmas to deserve such a concentrated speech.
The decision not to select it as best picture at the Ariel Awards for 1952 was a wise one.
