Unimatrix Zero, Part 2
Unimatrix Zero, a cyberspace enclave for certain Borg within the collective, is under threat by the Borg Queen who wants it destroyed at any cost. Meanwhile, with Janeway and her crew going undercover as Borg drones in an attempt to infiltrate the Collective, the Borg Queen gets more and more desperate to unravel the mystery of Unimatrix Zero. She will even resort to the destruction of her own kind in an attempt to stop Janeway and Unimatrix Zero.
Seven of Nine shows some emotion when three of the four Borg children leave the U.S.S. Voyager, but the Doctor confirms that she may have malfunctioning ocular implants. The remaining young Borg, Icheb, then decides that he would like to join Starfleet Academy. When Seven later admits to suffering from some headaches, it is discovered that she needs a critical operation requiring Borg parts. However, it may be that the young Borg, Icheb, is the only one who can help her.
While Tom Paris and Harry Kim are performing tests on the new Delta Flyer, they encounter a mysterious pilot who challenges them to a race. The woman, Irina, later informs them of an upcoming starship race. Soon, the Starfleet officers find themselves involved in this race-an event intended as the first step towards peace between four different cultures from this area of space. But one of the racers is determined to sabotage the goodwill of the event.
The Doctor's program is stolen from the U.S.S. Voyager and he is forced to work on a large, multi-tiered hospital ship. While Captain Janeway and her crew try to find him, the Doctor decides to take matters into his own hands when dealing with the unethical treatment procedures for the sick and dying aboard the hospital ship.
Aboard the U.S.S. Voyager, former members of the Maquis appear to be singled out in a rash of violent attacks. Before long, the safety of the entire crew is in jeopardy. When Tuvok takes charge of the investigation he becomes frustrated at the lack of a logical motive, but soon makes some rather startling discoveries
The crew of the U.S.S. Voyager gets an unexpected bonus in their regular "mail" beamed from Starfleet in the Alpha Quadrant. When a hologram of Reg Barclay appears telling the crew of a new plan that can get them home within days, everyone is elated. The plan seems dangerous in theory, but the Barclay hologram persuades the crew the risk is minimal. Meanwhile, back at Starfleet, the real Reg Barclay is completely unaware of his doppelganger's actions.
Flesh and Blood, Parts I and II
The U.S.S. Voyager answers a distress call from a Hirogen training facility, only to find a holographic environment littered with Hirogen corpses. The holographic technology given to the Hirogen by Captain Janeway for hunting training has been modified to the point where the prey have become the hunters. The holograms have not only become self-aware, but are essentially a new race, seeking refuge from "organic" slavery and brutality. Seeking to liberate one of "their own," the holograms kidnap the Doctor, who soon finds himself torn between his loyalties to Voyager and his holographic brethren.Body and Soul
While performing experiments on the Delta Flyer, Seven of Nine, Harry Kim and the Doctor are attacked by a Delta Quadrant race who view "photonics" such as the Doctor as mortal enemies. With time running out, the Doctor must hide in plain sight - taking refuge in Seven of Nine's Borg implants! Taking over her consciousness, the Doctor must convincingly behave as Seven of Nine to survive.
It's not easy being a parent, even for a Q. Because Captain Janeway and the crew of the U.S.S. Voyager were so instrumental in Q's quest to have a child, he decides to make "Aunt Kathy" teach his son some responsible virtues. Although appearing to be fully grown, the younger Q proves harder to handle than his irascible father, and with his omnipotent powers, disciplining the youngster proves not only impossible, but exceptionally dangerous as well.
As the U.S.S. Voyager gets closer and closer to the Alpha Quadrant, a new means of direct yet brief communication with Starfleet is established, allowing the crew a few minutes each to communicate with family and friends. The Doctor may not have any family or friends on Earth, but he does have a holo-novel to pitch to publishers — the story of a ship stranded on the other side of the galaxy with a strangely familiar crew; a crew that barely tolerates their holographic doctor who lives in virtual slavery.
Now that regular communication between the Alpha and Delta Quadrants is possible, Starfleet has a mission for the crew of the U.S.S. Voyager — locate and retrieve the old Earth probe "Friendship One." Launched in the late 21st century, the probe's trajectory places it somewhere near Voyager's current position, but no one predicted what a Delta Quadrant civilization would do with the probe when they found it.
Chakotay and Seven of Nine are stranded amongst a primitive people when their shuttle encounters an energy barrier that prevents Captain Janeway and the U.S.S. Voyager from locating them. The only solution they can attempt would violate the Prime Directive and pollute the native culture. Meanwhile, Tom Paris takes a wrong turn that could cost him valuable time.
When the U.S.S. Voyager encounters Talaxian lifesigns on a long-range scan, Neelix is understandably excited at the prospect of encountering people of his own race, whom he'd thought he'd left far behind. What they find when they arrive at the source of the sensor readings, a mineral-rich asteroid field, will forever change life for the entire crew of Voyager.
When Delta Quadrant beings take Captain Kathryn Janeway hostage, it's up to The Doctor to fulfill the requirements of their ransom: the U.S.S. Voyager warp core itself. The Doctor must fool his crewmates by holographically assuming their identities, knowing that one false move will result in the immediate execution of his Captain.
Endgame, Parts I and II
It took the U.S.S. Voyager decades to journey home from the Delta Quadrant, decades which took their toll upon the ship's crew and Captain. Now an Admiral in Starfleet, Kathryn Janeway cannot reconcile the price of the long passage, and embarks on an ambitious and forbidden plan to change the past, forcing a final confrontation with Voyager 's deadliest enemy.
