Although Carlos Ramirez is on maneuvers with the Marine Corps Reserve, he doesn't change his style of living with steaks, champagne and pretty girls. The tough commanding officer, Captain Dolger, learns Ginger, the pretty redhead, slipped through security on Carlos' yacht and makes plans to court-martial him. Carlos finds that the Captain and Mother Superior are old friends and sends an SOS to Sr. Bertrille. Mother Superior reluctantly allows her to go to Carlos' aid. Her approach is tracked by radar and she is fired upon, but fortunately with blank ammunition. Somewhat shaken, Sr. Bertrille talks to Carlos but is discovered by the Captain. He can't believe she flew over and thinks she is working with Headquarters to test his outfit's security. Although Mother Superior confirms Sr. Bertrille's story, the Captain still thinks it's a plot and asks Sr. Bertrille to fly, but she can't, there is no wind. The opposing Aggressor's landing craft is sighted and the Captain hurries to action. Carlos insists Sr. Bertrille escape. She goes aloft, spots another Aggressor force approaching from another direction and alerts Carlos. The Captain doesn't believe Carlos but is convinced when he spots Sr. Bertrille soaring overhead. He deploys four units who capture the Aggressors. The maneuvers successfully concluded, the Captain is shattered to find one of Carlos' girl friends in an Aggressor uniform.
