I came across this episode on TV yesterday;

Starfleet is a warmonging Star Empire, the Enterprise crew looks like a group of radical military, the Vulcans are slaves, all the female crew members are sexily dressed including T'Pol and there is a Federation Starship from the future, U.S.S. Defiant!!

At the end, Ensign Sato kills Captain Archer and takes command of the U.S.S. Defiant; warps back to Earth and demand they surrender to her, the new Empire Empress.

What happens after that?

The 2-part Episode ends!!

Is this the only episode of Star Trek Enterprise with this storyline?

thanks!!
