Based on a true story, this Spanish historical drama takes place during the Spanish Civil War, telling the tale of newlyweds who spend 33 years hidden away in their home to avoid possible retaliation. That may not sound like a terribly compelling plot, but this film manages to justify its 147-minute runtime by developing near-constant tension and accurately depicting the fear felt during that time in the country's history.
