Description: On August 10, 2017, in an event that transfixed the world, Danish inventor Peter Madsen brutally murdered Swedish journalist Kim Wall on his homemade submarine in the waterways outside Copenhagen. A year earlier, filmmaker Emma Sullivan had started documenting Madsen; his projects, including building a rocket to become the first amateur astronaut; and the group of enthusiastic helpers drawn to his workshop to help build them. Through this shocking sequence of events and astonishing filmmaking by Sullivan, the horrible truth of what happened to Wall can be told as never before. [Sundance]
