In August 2017, Swedish journalist Kim Wall boarded a homemade submarine in Copenhagen for an interview with Danish inventor Peter Madsen. She was supposed to be back in two hours. She never returned.

This is the story of Kim Wall - an accomplished journalist who traveled the world telling stories about people others overlooked. It's about the investigation that followed her disappearance, the trial that exposed the truth, and how her family made sure she would be remembered not as a victim, but as the fearless reporter she was.
