The 100 is a post-apocalyptic science-fiction television show, about a large group of people living in a space-station orbiting Earth, 97 years post-nuclear war (or as it is referred to in the context of the programme, Putin's Punch-Up). The Ark's technology is never fully explained (and for all we know, it was built by pathetic nerds who realised that they could actually be productive when Uncyclopedia went down for an afternoon). To buy time, and to see if the world is inhabitable, The Ark's leaders send a group of 100 juvenile delinquents down to Earth.
