The story focuses on a quadrilateral of characters: the Republican soldier Lluis (Marcel Borras), his wife Trini (Bruna Cusi), his buddy Soleras (Oriol Pla) and the local aristocrat, the Carlana (Nuria Prims). We meet the Carlana first as she barely escapes with her life when an anarchist army overruns the Carlan's estate and executes him. She convinces the soldiers that she was just a sexually-exploited maid, and now she continues to occupy the property. Looking to her children's future, she wants them recognized as legitimate heirs to the land. As no witnesses to her marriage to the Carlan to survive, she looks to Lluis to help persuade some local peasants to perjure themselves by swearing under oath that they witnessed the wedding. She's made it clear to lonely Lluis, far from home and wife, that helping her with this is his best chance at getting to ride more than the Carlan's horse.
Lluis and Trini try to reconcile but their child's illness brings a new crisis. Medicine for diphtheria is in short supply on both sides of the war, as Soleras unhappily admits, but someone of the Carlana's standing can deliver the goods -- for a price. The price she extracts from Lluis for his son's life is Soleras's death. Fortunately, Soleras is more willing to pay that price than Lluis did, but what good does any of this do anyone while the war grinds on. A closing air raid blends into newsreel refugee footage, with some of our actors added, to suggest that any victory in such an environment is only temporary.That's the moral of this vividly shot picture -- cinematographer Josep M. Civit runs the gamut from the funereal darkness of the crypt to the blazing light on the landscapes. It's more a sensational, psychological piece than a historical or political drama: the foreign viewer won't learn much about the civil war from Uncertain Glory, apart perhaps from how it was experienced on an unideological individual level. You don't really need to know what any side stood for to appreciate the film's human drama and its dramatically picturesque presentation. At a time when societies everywhere seem to be coming apart, it might seem less like a period piece and more like a premonition in its gothic timelessness.
