The 100 (2014)

Post-apocalyptic US drama series set 97 years after nuclear Armageddon decimated planet Earth, destroying all civilisation. The only survivors were the 400 inhabitants of 12 international space stations that were lucky enough to be in orbit at the time.

Since then, three generations have been born in space and the population has swelled to thousands on the 'Ark', the dozen stations now linked together and repurposed to keep the survivors alive.

Life on the Ark is hard. Population is tightly controlled, resources are severely rationed and all crimes, no matter how petty, are punishable by death - unless you're under 18.
