Cautiva 2004 on netflix

Cristina’s life is thrown into turmoil when she is suddenly escorted from her strict Catholic school in Buenos Aires and told that she is really Sofía Lombardi, the daughter of activists who disappeared in the ’70s. Questioning everything she once thought true, Cristina embarks on a journey to find her true identity. Meeting others like herself, the young girl soon discovers the real-life horrors of Argentina’s relatively recent past and the nightmare that claimed tens of thousands of lives during the country’s “dirty war.”
