Ranch foreman Steve Rideen (Starrett) and his sidekick Lucky (Hayden) get caught up in a brawl at Baltimore Bonnie's (Walters) saloon. It's a ruse set-up by her ex-husband Seth McBride (Bennett) so he can clean out her safe. Ruined, Bonnie, along with Steve and a wounded Lucky, take refuge in a wagon train. Unfortunately for them, McBride is close by with a wagonload of guns he intends to sell to the Indians, which results in a lot of trouble.
