Through the 1980s and 1990s, violent anti-Castro groups based in Florida carried out hundreds of military attacks on Cuba, bombing hotels and shooting up Cuban beaches with machine guns. The Cuban government struck back with the Wasp Network — a dozen men and two women — sent to infiltrate those organizations. The film tells the story of those unlikely Cuban spies and their eventual unmasking and prosecution by US authorities. Five of the Cubans received long or life prison terms on charges of espionage and murder.
