Three-hundred-year-old Commander Marion has begun a new commission as the commander of two star systems. As she shuttles back and forth from Helion 3 to Roma 2 she is drawn into a wormhole that sends her back to the nineteenth century. There she is pursued by Major Thomas Conrad, a Union officer, who is determined to capture her. After finally finding her way back to her shuttle, she recalculates her wormhole reentry only to find herself shot down in World War Two Europe. There she is rescued by a sympathetic Major Thomas Conrad, who turns out to be the grandson of her former pursuer.
