At the end of the 24th Century, and 14 years after his retirement from Starfleet, Jean-Luc Picard is living a quiet life on his vineyard, Chateau Picard. When he is sought out by a mysterious young woman, in need of his help, he soon realizes she may have personal connections to his own past.

Picard begins investigating the mystery of Dahj as well as what her very existence means to the Federation. Without Starfleet's support, Picard is left leaning on others for help, including Dr. Agnes Jurati and an estranged former colleague, Raffi Musiker. Meanwhile, hidden enemies are also interested in where Picard's search for the truth about Dahj will lead.
