That's actually a great movie plot, not sure if it has been done before.
Not with Voyager, but for example:
The year is 2243; a spacecraft that humans sent out of the solar system on a one way trip launched in 2045, has once again come into contact unexpectedly and is re-entering our solar system. The system seems to have been updated and is sending information that would have not existed when it was launched and is potentially foreign tech in 2243.
This ship was never supposed to come back...
Edit: Ok, I have admittedly not seen the first Star Trek movie.. I probably should =p
Rather belatedly the human race realizes - after decoding some interstellar video - that the Voyager's trajectory will bring it sooner or later into contact with a race whose sole mission is to eradicate all other intelligent life.
The Voyager's creators helpfully adding a map indicating its origins prompt the recall of the century: launch a mission to overtake both Voyagers and to capture them and bring them back before they are discovered.
Upvoted purely because I love the fact that there's someone here who hasn't seen ST:TMP.
(And you needn't bother, honestly. It's the franchise's answer to 2001, put together by people who didn't really get what made 2001 great. If, like me, you can't get enough absurdly prolonged sequences of old-school practical model effects in effectively static poses, then you'll love it to pieces, but otherwise...)
You just described the plot of the first Star Trek film. Even better, it was a Voyager probe (a fictional Voyager 6) that was augmented by alien machine intelligence and returned to Earth.
That's fanon. Yeah, I sort of like the idea too, and yeah, Goldsmith to some extent may have styled the First Contact Borg leitmotif after V'ger's from TMP, and yeah, maybe he did that deliberately, and yeah, somebody's friend of a friend said that Gene Roddenberry once coughed in a way that could be interpreted as suggesting he'd had in mind the Borg creating V'ger all along - but it's fanon all the same.
(Me, I like Ron Jones's theme from The Best of Both Worlds a lot better, anyway...)
