In 1978, the militant Tulio Valenzuela was kidnapped in Argentina, along with his partner Raquel ─pregnant─ and their little son. At that moment, General Galtieri proposes that they save their lives in exchange for traveling to Mexico and handing over the leadership of the Montoneros. There, Tulio escapes and denounces the Argentine military. He knows that with this fact, Raquel will have a tragic end.
