Actually - they are in it and the spoiler was kind of right - but its not the same and actually they did not a bad job of ending it.
Helps if you watch the Next Generation episode (which incidentally Sky had on just the other day) called The Pegasus for some background infomation (THIS IS NOT A SPOILER THOUGH) (Episode 164 according to Amazon) in which Commander Riker (Jonathan Frakes) meets up with his old captain (Terry O'Quinn), now a Starfleet admiral, from the Federation ship Pegasus. He orders Riker not to share the true purpose behind an Enterprise mission to salvage the Pegasus: retrieving an advanced cloaking device that is illegal under Federation law. But when the technology is used to phase the Enterprise inside an asteroid (where it partially fuses with solid rock).
I got that as well from Amazon BTW
