Six beautiful women are on a train en route to Sunshine Hill in the early 1800s. When the train is hijacked by robbers and the soldiers on board are caught unaware, another surprise is in store: these lovely ladies can fight! Margaret Hart is a young woman determined to become a sheriff, and takes on the fight, although she is somewhat lacking in experience. She gains plenty on this trip, however, and the ragtag team of Western warriors joins forces with another passenger, Spencer, to fight some nefarious bandits and guide the train to safety.
