The first outdoor film to be shot in three-color Technicolor. Two backwoods Kentucky clans, the Tolliver and the Falins, have been feuding so long no one remembers what started the fuss. But young engineer Jack Hale (MacMurray) gets stuck in the middle when he comes to build a railroad through the Blue Ridge Mountains. Hale saves the life of Dave Tolliver (Fonda) but Dave's not happy when the city slicker starts mooning over Dave's sister, June (Sidney). And the Falins aren't happy about the railroad, which leads to even more fighting. Based on the novel by John Fox Jr. and previously filmed in 1916 and 1923.
