What is the story of the Under Salt Marsh?
Sky
In Under Salt Marsh, Kelly Reilly portrays a former detective named Jackie Ellis who lives in a small town filled with friendly faces and endless trust. After all, no one locks their doors at night, since everyone's basically one big family. But what happens when a mysterious death and a missing person’s case cause the small town to erupt with suspicion and chaos? Will Reilly be able to solve the case, or is it way too personal for her?
The new trailer shows off the connections of all the characters in town, and the effect the missing person's case has on the town. I always feel like shows are more convincing when there's a large ensemble that you really believe care about each other. This is definitely one of those shows!
I don't know about you guys, but the trailer has reeled me in. This seems exactly like the kind of show that'll have me on the edge of my seat every episode, and like it'll fill the void left behind by Broadchurch. Crime shows never go out of style, and with such a beloved Yellowstone star leading this one, I can imagine it's going to be a massive success.
