In the 1953 classic Bend of the River, reformed border raider Glyn McLyntock, played by James Stewart, is leading a group taking food and other supplies to a settlement that will starve without it.
Alas, he's double-crossed by his hired men, including a young Henry Morgan, and his friend, Emerson Cole, played by Arthur Kennedy. Here, Kennedy saves him from being killed and sends him on his way, taking the food to sell to a mining camp willing to pay much more for it.
Cole's going to regret that before too much longer. Unarmed, alone and on foot, McLyntock is going to get that wagon train back. Just you watch.
