Plot Summary: As Hitler arrives in New York, the Nazi general headquartered in the White House demands the squadron promised to him by the aliens and is informed that if he is not more accommodating, he and his people may be erased from history. In private Vosk concedes that he does not trust his Nazi allies. The aliens have realized that Tucker and Mayweather are not temporal agents, but they don't believe their presence on Earth in this era could be an accident. On Enterprise, Alicia begs Archer to bomb Berlin with his ship's weapons, but he insists that this is not the way to defeat their common enemy and asks for her help in finding his missing crewmembers.
Vosk contacts Enterprise, telling Archer that he will hand over Mayweather and Tucker if Archer will agree to meet with him. After beaming a rather battered pair of Enterprise crewmen back aboard, the captain listens to Vosk's plea for assistance as Vosk insists that Daniels and his people manipulate the timeline just as shamelessly as he does and they have agendas as well. If Archer will help him, Vosk promises, he will set Earth history as it was before any temporal agents began to interfere. Back in sickbay, Archer begins to tell Tucker about the conduit and the temporal shield when a glimpse of Phlox's readout reveals to him that "Tucker" is not human; he struggles and fights with Silik, who has taken Tucker's form to sneak a disc of schematics of Vosk's facility aboard the only vessel present that could carry Silik into the future.
Vosk contacts Archer, telling him that a thief from Archer's era has stolen data belonging to him and that he is prepared to fire a plasma cannon at Enterprise to retrieve it. Archer refuses to make a deal, returning fire with phase cannons, but Enterprise is damaged. T'Pol discovers that the crew cannot pinpoint the location of the conduit, nor can they disable Vosk's shields from orbit. Silik tells Archer that although he has no interest in saving the life of the man whose form he took to escape from Earth, he does not want Vosk to succeed in completing the conduit and will help Archer sneak into the facility where the device is being constructed so that Archer can place a homing beacon for Enterprise. Alicia recruits mobsters in the American resistance movement to help Archer and Silik get past the Nazis guarding the building.
Vosk makes a speech about how temporal manipulation will allow his people to perfect themselves, then prepares to use the finished conduit to reach the 29th century. When he learns that the facility has been breached, he breaks the alliance between the aliens and the Germans and sends his enhanced squadron of jets, originally promised to the Nazis, to fight off Enterprise, which has entered the atmosphere to blow up the facility after honing in on the signal Archer has planted. But ionization in the atmosphere is blocking Archer's communications with the ship, and Silik is shot and killed by the Nazis. Just afterward, Archer finds Tucker, who has escaped from the corridor where Silik left him. The two return to the ship, where Archer orders Reed to fire on the facility. It blows up just as Vosk enters the conduit, killing him.
Daniels, who is alive and healthy again, shows Archer the timeline resetting, but Archer is unimpressed, begging to be sent back to his own era and to have his crew left out of the temporal cold war. He and his crew can see Earth on the viewscreen but they are uncertain which era they have entered until signals start coming in, and dozens of friendly spacecraft approach Enterprise.
