It's Kate's birthday. She is grateful for all the presents and the birthday good wishes, but she is hoping to receive something from Betty Jo and Steve who are still on their honeymoon in Hawaii. But the mail comes and goes with no gift from the honeymooners. Kate starts to believe the two have forgotten her birthday. Meanwhile, Betty Jo and Steve hope to fly home early and in time for Kate's birthday. Sam and Joe decide to go to the Pixley post office to see if anything for Kate is held up there. Because they tamper with the mail there, the two wind up in jail. Betty Jo misplaces Kate's present, and while looking for it, they miss their connecting flight. Thanks to an Air Force buddy, Betty Jo and Steve make it back in time.
