The following contains spoilers for Star Trek: Picard Season 3, Episode 10, "The Last Generation," now streaming on Paramount+.
Star Trek: Picard has finally reached its end, with cinematic action set pieces and standout character moments for all of its main characters as they set out to save Earth from the Borg Collective and the Changelings. At the helm of the restored USS Enterprise-D, Jean-Luc Picard moves to rescue his son Jack from the Borg as the assimilated Starfleet armada moves forward. And not only does this provide the Star Trek: The Next Generation crew with a thrilling sendoff -- the Picard series finale promises an exciting new beginning.
Pavel Chekhov’s relative Anton sends out a distress signal warning Federation vessels to stay away from Earth because the planet’s orbital defenses have been obliterated; both Spacedock's and Earth’s shielding is being bombarded by the armada. The Enterprise detects a Borg signal emitting from a Borg Cube hidden in Jupiter’s Great Red Spot, with Picard and Beverly Crusher identifying the broadcaster commanding the subjugated fleet as an assimilated Jack Crusher. Picard commands the USS Titan to approach the Borg and destroy the beacon, which would effectively sever its broadcast and free the assimilated from its control.
Beverly pinpoints Jack’s location on the Borg Cube. Picard, Will Riker and Worf board it to destroy the beacon personally and rescue Jack from the Borg Queen’s insidious grasp -- the latter objective carried out by Picard alone. The Queen informs Picard that it was Jack’s presence on the far side of the quadrant that revived them from the virus Kathryn Janeway infected them with, with the Queen forced to cannibalize her own collective to survive. Vengeful over the condition she’s been left in, the Queen is determined to use her new collective to annihilate rather than assimilate. She activates a small number of drones to defend the beacon while the Cube’s weapons attack the Enterprise.
Seven of Nine and Raffi Musiker lead a small strike force to retake control of the Titan, isolating the assimilated on the starship to sealed transporter rooms while careful not to give away their actions to the other starships. Using the Titan’s retrofitted cloaking device, Seven distracts the Borg with a strafing run -- but Spacedock is still destroyed, causing the last of Earth’s shields to deactivate. The confined assimilated break free and disable the cloaking device, leaving the Titan exposed and cornered while the armada begins to target population centers around Earth.
Beverly destroys the Cube’s surface defenses before Data pilots the Enterprise to the location of the beacon at the Borg vessel’s core, provided by Riker and Worf. As the beacon is destroyed and the resulting shockwave begins to overtake the rest of the ship, Picard assimilates himself again to communicate with Jack from within the collective. He liberates Jack, the two reuniting with Riker and Worf in the nick of time to return to the Enterprise. The Queen’s destruction reverses the assimilation of the young Starfleet personnel, prompting them to immediately cease their attack on Earth.
In the aftermath, Beverly rejoins Starfleet and develops technology to purge any lingering Borg influence from those affected as well as detect the evolved Changelings continuing to hide within Starfleet ranks. Tuvok is found safe and sound and pardons the Enterprise crew for the crimes they committed to save the day. He promotes Seven to captain the Titan, which is rechristened as the Enterprise-G, with Raffi and Jack officially joining its crew. But as the old Enterprise-D officers reunite over an impromptu poker game back at Guinan’s bar, Jack is confronted privately by Q... who informs him that his trial for humanity has only just begun.
Created by Akiva Goldsman, Michael Chabon, Kirsten Beyer, Alex Kurtzman and Terry Matalas, all three seasons of Star Trek: Picard are available to stream in their entirety on Paramount+.
