A young and cynical female journalist learns love may transcend trials and time as she discovers a story that will change her life forever. When war separates lovers on their wedding anniversary Feb. 14, 1944 at LA Union Train Station, Navy pilot Neil Thomas makes a promise he isn't sure he can keep - to return to the train station safe by their next anniversary. For sixty years Caroline Thomas keeps her promise by waiting at the train station until her missing in action husband can finally keep his with the "lost valentine." The message and meaning shows romance and love can be real; worth fighting, and maybe even dying for.
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. Naval pilot Neil, 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.
