re: What is your favorite Star Trek TNG episode?

I can't remember the name of it, but it is the one where Riker's former captain, who is now an admiral, comes onboard to command a mission to an asteroid where there is secret illegal cloaking technology that the admiral needs to recover and cover up before the other race that is also hunting it down finds it.

The admiral expects Riker to participate in the cover up since he was apart of the initial operation where he led a mutiny, if I remember correctly. Riker commits what he thinks is suiciding his career by telling the truth to Picard.
