A Union Cavalry outfit is sent behind Confederate lines in strength to destroy a rail/supply center. Along with them is sent a doctor who causes instant antipathy between him and the commander. The secret plan for the mission is overheard by a southern belle who must be taken along to assure her silence. The Union officers each have different reasons for wanting to be on the mission.—John Vogel
