The series opens with the starship Voyager in the middle of a battle with the Dominion during the final days of the Dominion War. Things get really bad to the point in which the crew almost believes they wouldn’t able to make it until they come across a wormhole. They go through the wormhole to escape the Dominion and they end up in some unknown region of space. When they try to get it back to where they were before, they find no sign of the wormhole they traveled through. It isn’t until the end of the first season that the crew discovers they haven’t traveled to an unknown region of space but that they were sent 300 years into the future at a time where the Federation has long since fallen and the galaxy has fallen into utter disarray.
