Commander Key Weedon, a
pilot with the U.S. Navy, is sent to investigate when an S.O.S. emergency signal is spotted in the San Diego area near
NAS North Island. He discovers it is the doing of a six-year-old boy, Grover Martin, whose Uncle Simon, an airline pilot, gave the boy a blinker light as a gift. The child's mother, Amy, is an attractive widow, and Key develops an immediate interest in her. Her three sons also enjoy the attention Key gives all of them. Amy has a blind spot when it comes to naval officers, however, not wanting a permanent relationship with one because they are constantly on the move. She had been a military child herself, and missed not having permanent "roots". Sure enough, Key gets orders to go to Italy, so Amy refuses his marriage proposal, though they love each other. Uncle Simon has a new treat for Grover and his brothers. He ties them to helium weather balloons and flies them as one would a kite. Unfortunately, Grover unties his tether and he goes floating for miles over San Diego. Large-scale rescue operations are quickly organized by the Navy, and it turns out to be Key himself who lowers himself on a rope ladder from a
Navy blimp to rescue the boy. A grateful Amy then decides that wherever he goes, Key is the man for her. ==Cast==
