White Wall

Tunnel C6 (1x1)

Air date: Sep 20, 2020

A piece of mysterious white wall is found deep underground, causing an accident at the mining site of the world's largest final depository for nuclear waste. The director of the project, Lars Rapp, wants to keep the find a secret, but rumours spread quickly in the small boom town that has sprung up around the site. Also, an environmental activist was found flying a drone above the mine just before the accident. She may have dropped something dangerous on the site, maybe even a bomb?
