A deeply unsettling true-crime documentary that uses intimate access to a killer and his circle to explore complicity, betrayal, and the moral weight of witnessing evil.

In 2016, a young Austrialian filmmaker began documenting amateur inventor Peter Madsen. One year in, Madsen brutally murdered Kim Wall aboard his homemade submarine. An unprecedented revelation of a killer and the journey his young helpers take as they reckon with their own complicity and prepare to testify.
