Operación México, un pacto de amor.

In a turmoil-torn Argentina, in the summer of 1978, Edgar Tulio Valenzuela (Tucho) and Raquel Negro (María), heavily pregnant with a young son, are kidnapped by the Armed Forces and taken to the outskirts of Rosario. A high-ranking Argentine Army officer makes Tucho a proposal that, if he follows it, will betray the ideals to which he dedicated his life. If he rejects it, he will lose his wife, his son, and the children his future holds. They love each other beyond all reason and circumstance. María and Tucho make a pact... and amidst betrayal and horror, a love story that will last forever is born.
