Navy widow Amy Martin lives near Halsey Field - a naval base - in San Diego with her three adolescent sons, Luke Martin, Alex Martin and Grover Martin, and Grover's imaginary friend Harrigan. Amy has been around the navy all her life having been a navy brat. Despite missing their brother and son, Amy's nearby sister-in-law and father-in-law, Tandy Martin and Captain Martin, want Amy to move on with her life by getting remarried. They believe their wish for Amy may be realized when she meets Navy Commander Key Wheedon, who is stationed at Halsey Field. The two, attracted to each other, begin dating despite Key stating that he is not the marrying type, and Amy stating that she wants a more stable life for her sons than what a military life offers. Regardless, the two end up falling in love. But when Key announces that he has been assigned to a naval base in Italy, they have to decide if there is indeed a future for them despite their earlier assertions. A plan executed by Grover and Harrigan, with a little unwitting help by Amy's visiting airline pilot brother Cy, may make Amy and Key understand what is best in this situation.—Huggo
