Homesteaders Mace Corbin and Clyde Moss pick up much needed dynamite and begin a journey to transport it from an army fort to their homes, hiring a crew of ex-soldiers just released from the army prison. Mace knows he's got his work cut out for him with unstable dynamite, undisciplined hired hands and possible hostile Indians but he doesn't have the slightest hint that his trusted friend Clyde has betrayed him.
