This is probably the scariest movie I have ever seen. This documentary chronicles the terror and confusion scientists working with nuclear waste are faced with. The dilema: how to store nuclear waste. Since it is radioactive for 10,000 years they propose to bury it deep into the Earth. Well it goes on from there, with scenarios trying to imagine what might happen, if years from now someone was to open the storage facility. How to communicate to unknown people who might not even speak English, or any known present language.
