Llegaron de noche (2022) on Netflix

Plot summary

El Salvador, 1989. The civil war has run for a decade, and the Jesuits of the Central American University are expected to play a part in the peace agreement the war is moving toward. One night six of them are killed on campus, and word of the killings reaches outside the country almost at once. Lucía, who works on the university's cleaning staff, is there and sees who did it. The government blames the guerrillas, and she is the eyewitness who contradicts that account. Speaking means going against the official version in public; staying silent keeps her family safe from the consequences.
