Lucas Thomas’s grandmother Caroline returns every Valentine’s Day to the station where, at their first wedding anniversary, she waved off to the Pacific Theater of War in 1944 her husband Neill, a US Navy pilot who is still officially missing in action. Lucas, a former baseball star and reputable physiotherapist about to publish, tells the story to a station manager who assigns the item to Susan Allison. She gets involved and befriends Caroline, but resists her crush on Lucas on account of an already soulless engagement with international reporter Andrew Hawthorne. Caroline’s mild cardiac crisis seems to ruin everything.
