Rent Into Eternity (2010)

In Finland the world's first permanent repository for high-level radioactive waste is being hewn out of solid rock. A huge system of underground tunnels is being constructed, tunnels which must last through natural disasters, man-made disasters, and societal changes for 100,000 years. Captivating, wondrous and extremely frightening, Into Eternity takes viewers on a journey never seen before into the underworld and into the future.
