The 100 (5th season) (trailer).

Ah, the 5th season of scifi TV series The 100 rises on the horizon, along with its accompanying trailer. Complete with future ruined post-nuclear apocalypse Earth, down to one last inhabitable valley, now, and where every survivor looks like a male/female supermodel in their twenties. American, of course.

On US TV April 24th 2018 on The CW, shortly thereafter on British TV, too (Channel 4, was it?).
