What it is
Ninety-seven years ago, nuclear Armageddon decimated planet Earth, destroying civilization. The only survivors were the 400 inhabitants of 12 international space stations that were in orbit at the time. Three generations have been born in space, the survivors now number 4,000, and resources are running out on their dying "Ark" - the 12 stations now linked together and repurposed to keep the survivors alive. Draconian measures including capital punishment and population control are the order of the day, as the leaders of the Ark take ruthless steps to ensure their future, including secretly exiling a group of 100 juvenile prisoners to the Earth's surface to test whether it's habitable.

Among the 100 young exiles are Clarke, the bright teenage daughter of the Ark's chief medical officer; the daredevil Finn ; the brother/sister duo of Bellamy and Octavia, whose illegal sibling status has always led them to flaunt the rules, the lighthearted Jasper and the resourceful Monty. Technologically blind to what's happening on the planet below them, the Ark's leaders - Clarke's widowed mother, Abby ; Chancellor Jaha ; and his shadowy second in command, Kane - are faced with difficult decisions about life, death and the continued existence of the human race.
