A River Runs Through It is a 1992 film about two sons of a Presbyterian minister â one studious and the other rebellious â as they grow up and come of age in a time that roughly spans the Prohibition era (1919-33) in the United States: from World War I (1917-18) to the early days of the Great Depression (1929-41). Eventually, all things merge into one, and a river runs through it. 2  The river was cut by the world's great flood and runs over rocks from the basement of time. 3  On some of those rocks are timeless raindrops.
