Spoiler.. This is the (Excellent) Series "The 100" (Kind of like a space age Game of thrones). This is the VERY LAST SCENE of the current series.
If you're going to start watching this series then DON'T watch this as it will spoil the whole shooting match
As I've just stated, I've been watching "The !00". The storyline is that Nuclear War happened but various countries "escaped" into orbiting space-stations.. or Arcs as they are called. It's going to take 100 years for Earth to be re-inhabitable again. The "Spacers" quickly realise they need to join with other "Spacers" to pool resources so all the spacestations dock (Except 1). What becomes clear after 97 years is that they are going to run out of resources and air before the 100 years are up. they are already having to make ANY crime no matter how trivial a capital offence. Basically crims are put in an airlock and jettisoned (floated). But it aint enough, by an order of magnitude. If your a crim and UNDER 18 you don't get floated, you get put on a prison wing.
And so the decision is made to "test" Earths inhabitability by choosing 100 young crims and sending them to back to Earth.
It's exciting and heart renching. Watchout for Murphy. Oh and Octavia kicks Butt
