"Vanessa has always been the bravest of all of us. Something was wrong with her the few months after she was stationed at Fort Hood. Not being able to sleep, losing weight. She would tell me that things were not what they seemed,” said one of sisters of Vanessa Guillén in the trailer for the new Netflix documentary I Am Vanessa Guillén.

The feature film tells the story of the 20-year-old Hispanic woman, and United States Army soldier, who was sexually harassed and murdered by another soldier. It all happened at one of the most important military bases in the United States, Fort Hood, on April 22, 2020, when the 20-year-old disappeared. Two months later, her body was found in a field near the same military base.

At first, the investigations pointed to another soldier, Aaron David Robinson, as responsible for the crime, but he committed suicide as he was about to be arrested by the police.

Since then, Guillén's family has demanded that the crime not go unpunished. The sisters of the victim, Lupe and Mayra Guillén, have been the visible faces of a collective claim, supported internationally by victims of sexual assault, in search of a historic military reform that ends harassment and sexual crimes in the U.S. Army.

“I am proud and honored to represent Vanessa Guillén, the family of Vanessa Guillén and thousands of brave soldiers and their patriotic families. I will continue to fight for the victims, our military, and all those who need and deserve a voice in this world," attorney Natalie Khawam wrote on Twitter.

The documentary I Am Vanessa Guillén is directed by the American filmmaker Christy Wegener.

“This is, at its core, a story about overcoming the greatest adversity imaginable in the name of family, love and justice. It's David against a bestial Goliath. Taking on the United States Army, one of the largest and most powerful institutions in the country, is no easy task. In making the film, it was incredible to see how a family forgot their pain in the most tragic moment of their lives to jump into the fray and fight for the greater good," Wegener said in a statement.

The feature film will premiere on Netflix on Nov. 17.
