I checked this out on a whim and was VERY impressed.

It's a Danish show.

Basically it starts raining one day in Denmark, and then bodies start dropping.

One family gets to safety in a bunker seemingly designed for such a disaster.

Things progress from there.

This plays out like The Walking Dead, only trade in zombies for lethal rain.

It takes several turns that I didn't see coming at all.

Highly recommend.
