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.
