An Army general announces he is taking over the wagon train and requiring all members to act as soldiers in helping him rescue a trapped cavalry garrison of 120 men who are otherwise likely to be slaughtered by hostile Utes. Flint, temporarily in charge of the wagon train, has little choice but to agree to the general's demand, as much as he hates it and his passengers want him to fight back. Particularly upsetting to Flint is learning that the man who recommended this takeover was Jim Bridger, a legendary frontiersman and scout who mostly raised Flint and whom he idolized.
