Star Trek Picard 1x02 Maps and Legends - Plot synopsis: A flashback shows a normal day at Mars Utopia Planitia Shipyards 14 years earlier, followed by the deadly attack by the synthetics.
Following Dahj's death, Picard seeks to track her twin Soji down.
With the help of Laris, he investigates Dahj's apartment and finds it completely scrubbed.
Laris suggests that the assassins may have been part of the Zhat Vash, an organization even more secretive than the Tal Shiar that holds a deep-rooted hatred of synthetics.
At the Romulan reclamation site, a relationship between Soji and Narek is flourishing.
Picard appeals to Starfleet for a ship, but is denied by Admiral Kirsten Clancy.
Picard attempts to assemble his own crew, inviting Agnes Jurati and the estranged Raffi Musiker.
Meanwhile, Clancy informs Commodore Oh of Picard's request and asks her to look into it.
Oh notifies the (secretly Romulan) Lt.
Rizzo to have her undercover operative "stay on mission".
Via holo-communicator, Rizzo speaks to Narek, her operative and brother.
Rizzo warns Narek that if he does not persuade Soji to reveal the location of other synthetics, she would be forced to take more extreme measures.
