Undercurrent: The Disappearance of Kim Wall

Journalist Kim Wall sets out on her latest assignment: a submarine voyage off the coast of Copenhagen with enigmatic inventor Peter Madsen. But when friends and colleagues begin tweeting that Kim has disappeared, a search locates Madsen and a sunken vessel.
