Star Trek: Enterprise - Season 4

The fourth and final season of Star Trek: Enterprise helped bridge the gap between Enterprise and the future developments of Star Trek: The Original Series. Capt. Archer and his crew escape from an alternate timeline, the result of the continuing Temporal Cold War, in which the Nazis have invaded U.S. soil in 1944. In the normal Enterprise timeline, political upheavals have left relations between Vulcans, Andorians, Tellarites, and Humans in a state of near-disastrous chaos.
