Seizoen 4

  1. Having mysteriously survived the destruction of the Xindi superweapon, a battered Archer awakes to find himself back on Earth in the 1940s in the custody of Nazi SS agents, and learns that Nazi-uniformed aliens have successfully helped Germany invade the United States. When he manages to break free of his captors, Archer joins forces with American resistance fighters to unravel the conspiracy behind the occupation.
    Meanwhile, believing Archer sacrificed himself to save Earth, T'Pol and the battle-weary Enterprise crew attempt to figure out how to return to their own time. But then a near-dead Daniels appears and informs them that the future has been wiped out by a faction of the Temporal Cold War, the same faction responsible for the altered events on Earth, and they must be stopped.

  2. Archer reunites with his astonished Enterprise crew and learns from Daniels on his deathbed that a radical Temporal Cold War faction threatens to obliterate the timeline. Archer returns to the Nazi-occupied eastern United States of the 1940s, and enlists the help of resistance fighters Alicia Travers and Carmine to destroy a massive time machine under construction on the surface.
    Meanwhile, hoping to forge an alliance with Archer, alien leader Vosk releases his captured prisoners Tucker and Mayweather, but this forces temporal agent Silik to emerge from the shadows to pursue his own agenda against Vosk.

  3. As the Enterprise crew revels in a heroes' welcome on Earth, Trip joins T'Pol on a trip to planet Vulcan, excited to visit her home and be introduced to her mother T'Les. But when T'Pol becomes obliged to reconsider marriage to former fianc? Koss, the future of their relationship is put in question. Meanwhile, Archer must defend some of his morally questionable decisions during the Xindi conflict before a Starfleet Command panel of inquiry. Later, Phlox experiences prejudice against aliens while taking shore leave on Earth with Malcolm and Travis.

  4. After a dangerous group of genetically engineered humans called "Augments" escapes from their secluded planet intent on causing all-out war between Earth and the Klingons, the Enterprise crew is called into action and Archer enlists the help of criminal genius Dr. Arik Soong, the scientist responsible for creating the Augments.
    While searching for the Augments in the Borderland ? the volatile region between the Klingon Empire and the Orion Syndicate ? Enterprise crosses paths with a band of ruthless Orion slave traders, who kidnap T'Pol and eight other crew members off the ship so they can be sold at auction, forcing Archer to enact a risky rescue mission with Dr. Soong's help.

  5. Reunited with his genetically engineered creations called Augments, criminal scientist Dr. Arik Soong and his "children" break into the medical outpost where Soong once worked, to steal the embryos of hundreds more potential Augments with plans to build a superhuman army. They will go so far as to release the deadly pathogens stored at the facility, Cold Station 12, if the staff, headed by Dr. Jeremy Lucas, dares impede Soong's plan. Meanwhile, Archer and his crew search for clues to Dr. Soong's whereabouts on Trialas IV, the planet where he raised the Augments, leading them to find one of the doctor's less perfect children who was abandoned by his siblings.

  6. Enterprise pursues Arik Soong and his Augments across hostile Klingon space toward a planet where the geneticist intends to go back into isolation and raise an army of genetically engineered superhumans. But Soong's "children" revolt against him and plan a biological attack upon a Klingon colony, in order to incite retaliation against Earth.

  7. The Earth embassy on Vulcan is bombed, killing 31 humans and 12 Vulcans. Enterprise is called to the planet to help investigate, but the Vulcan High Command already suspects a dissident religious faction known as "Syrrannites." T'Pol learns from her husband Koss that her mother T'Les has been forced into hiding to avoid arrest ? because she is a Syrrannite. Koss also brings her a mysterious heirloom containing a map. Believing this is a message from T'Les, T'Pol and Archer set out to follow that map across a treacherous desert, without the High Command's knowledge.

  8. On a quest to learn the truth behind the bombing of the Earth embassy on Vulcan, Archer and T'Pol track down the Syrrannites, a revolutionary faction hiding in a desert sanctuary which includes T'Pau ? the prime suspect in the bombing ? and T'Pol's mother T'Les. The rebels are on the verge of being crushed by Vulcan High Command leader V'Las, but they are stunned to learn that Archer might hold the key to their survival.
