Lead actor Don Bolton practically faints from the sounds of gunshots while filming a war movie.  When real-life Colonel Peter Fairbanks visits the set with his beautiful daughter Tony, Don insults them by mistaking Fairbanks for an actor and ordering the makeup man to put mud on the colonel.  Smitten by Tony, Don convinces her to go out with him.

He soon proposes to her to keep himself from being drafted but backs out when the draft age is raised to thirty-five.  Tony is appalled when she discovers his ulterior motive, and to improve her opinion of him, Don goes to his local recruitment office to enlist, but discovers too late that he is dealing with a real enlistment officer, not the actor that he hired.

At training camp with his assistant Bert and manager Steve, Don visits Tony and her father, who is stationed there, and Fairbanks makes a deal with Don that if he can actually make the rank of corporal, he will consent to his marriage to Tony.  Don, Bert and Steve consistently get into trouble, however, and spend most of their time on kitchen patrol.  Tony, having fallen in love with Don, defends him to her father.

Finally, Don, Bert and Steve's sergeant leaves them behind to keep them out of trouble while the rest of the unit participates in war games.  The trio decides to change some of the signposts to help their unit win; however, the signs lead the troop directly into an artillery range.  Tony, who has been berating the three men as cowards, attempts to pass through the line of fire to save the troops, but when her horse throws her, Dan overcomes his fear of gunfire, even after being hit in the arm, and crawls through the firing range to head off the troops.  Don, Bert and Steve earn their promotions and Don and Tony marry.
