At the outbreak of the Spanish Civil War in 1936, young newlyweds Higinio and Rosa are worried about the risk of reprisal killings, as Higinio is a Republican. He hides in a hole underneath their house with his wife's help. Despite the constant threat of discovery, as the Falangists search for him, the couple's love helps them to remain resilient. Higinio becomes increasingly isolated in his hiding spot, where he stays until the 1969 amnesty. The story is told in chapter-like sections, each with titles alluding to the themes.
