Following the loss of their son, a retired sheriff and his wife leave their Montana ranch to rescue their young grandson from the clutches of a dangerous family living off the grid in the Dakotas.
This is a movie that may have been better told as a mini-series. There is a lot of story available to mine for the entire cast of characters. The movie does a good job of bringing those characters to life, but it still feels like it's only scratching the surface; only giving you a glimpse of what it's like for those characters. The movie is based on a novel, and I'm now more likely to go read the novel to see if more is revealed.
