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.
Completely unaware of her special nature, Soji continues her work and captures the attention of the Borg cube research project’s executive director. After rehashing past events with a reluctant Raffi, Picard seeks others willing to join his search for Bruce Maddox, including pilot and former Starfleet officer Cristóbal Rios.
The crew's journey to Freecloud takes a detour when Picard orders a stop at the planet Vashti, where Picard and Raffi relocated Romulan refugees 14 years earlier. Upon arrival, Picard reunites with Elnor, a young Romulan he befriended during the relocation. Meanwhile, Narek continues his attempts to learn more about Soji while Narissa's impatience with his lack of progress grows.
When devastating truths behind the Mars attack are revealed, Picard realizes just how far many will go to preserve secrets stretching back generations, all while the La Sirena crew grapples with secrets and revelations of their own. Narissa directs her guards to capture Elnor, setting off an unexpected chain of events on the Borg cube.
