Safety in 100,000 Years' Time

The subject of "Into Eternity" is Onkalo, the Finnish government's attempt to solve its nuclear waste problem by carving a vast, 4km-deep bunker out of solid rock to bury it in for at least the next 100,000 years. However, the film's focus is bigger. Instead of looking for cover-ups and conspiracies at the site, Madsen uses the existence of Onkalo to create a hauntingly beautiful meditation on the mortality of our civilization, asking the question: what do we say about ourselves when we create something that will outlast everything we understand? That may be the last thing that remains of our society?
