Anders Lund Madsen travels to Japan to see what it's like after the nuclear power plant in Fukushima blew up in 2011. Here he visits zombie-like cities and buildings that still stand as they did when they were abandoned. He also investigates what became of the Danish nuclear waste. And then he is allowed to go all the way down in Finland, where they may have found the solution to where the radioactive waste will be stored for the next 100,000 years.
