A River Runs Through It is a cinematographically stunning true story of Norman Maclean. The story follows Norman and his brother Paul through the experiences of life and growing up, and how their love of fly fishing keeps them together despite varying life circumstances in the untamed west of Montana in the 1920s.

In Montana, naive teenager George longs to escape from his broken home before his dysfunctional parents push him over the edge. When George meets pretty drifter Lucy, she easily convinces him and his friend Claude to join her on a road trip to Montana in hopes of breaking her brother out of jail.
