"The Woman Who Wasn't There" refers to the story of Tania Head (real name Alicia Esteve Head), who fabricated a dramatic account of surviving the 9/11 attacks despite never being in New York City that day. She claimed to have escaped from the South Tower, suffered severe injuries, and lost her fiancé in the North Tower. Head became president of the World Trade Center Survivors' Network, gaining sympathy and recognition before her story was exposed as a complete fabrication by investigative reporters and members of the survivors' community.

This story was documented in a film and a book both titled "The Woman Who Wasn't There," directed by Angelo J. Guglielmo Jr., exploring Head's rise, the unraveling of her tale, and the psychological motivations behind her deceit. The documentary offers insight into how trauma and the need for connection and recognition may have driven her to invent the story, even though she did not financially profit from it.

In summary, "The Woman Who Wasn't There" is a gripping real-life psychological thriller about a false 9/11 survivor whose deception had significant emotional impacts on the survivor community and the broader public.
