It is November 25, 1960, and three beautiful sisters have been found near their wrecked Jeep at the bottom of a 150-foot cliff on the north coast of the Dominican Republic. The official state newspaper reports their deaths as accidental. It does not mention that a fourth sister lives. Nor does it explain that the sisters were among the leading opponents of Gen. Rafael Leónidas Trujillo?s dictatorship. It doesn?t have to. Everybody knows of Las Mariposas--the Butterflies.
