The film was a farce of mostly embellished stories. The real truth in simple terms is that Trujillo had the Mirabal sisters killed. The story told by many was that they were killed because Minerva, one of the sisters refused the amorous advances by Trujillo. But in reality, the Mirabal sisters were involved in Anti-Trujillo activities and those who opposed his regime sometimes ended up in la 40 torture house or dissappeared.
Now, for the record, one of the Mirabal sisters was married to Tavarez Justo, a communist leader of the 14 de Junio Movement who was later killed in a military ambush during a guerrilla outing by Tavarez and his Castroist group. This relationship exacerbated Trujillo's hate for the Mirabals. Tavarez Justo, now a cult hero was nothing more than an ambitious bourgeois Ramfis Trujillo imitator, who even copied the way Trujillo wore sunglasses. He even looked slightly like Ramfis. He wore expensive clothes and was a bon-vivant, a regular trait among Dominican Communists. If you look at today's leftover Communists from that period, including their offspring, you will find that all of them are now avowed capitalists, very rich and powerful. Even Guido Mazzara, President Hipolito Mejia's Legal Counselor is the son of a top Communist leader who was killed in Europe supposedly by Balaguer and he is reputed to spend US$10,000 in cloths a month. Among some of the best dressed Communists is also Hector Aristy.
