Wounded, he climbs into a telegraph pole and asks through the telegraph wires for help from the fort. Bob's fiancée Edith comes along with the soldiers. The soldiers find only dead bodies and decide to chase the Indians. Edith stays behind to search for Bob. She finds him and together they return to the fort. The Sioux then attack the fort, but when the situation seems hopeless, the army returns and the Indians are expelled.
