Keiko has been possessed by a Pah-wraith, one of the evil spirits who dwell in the Fire Caves on Bajor.  Miles must do exactly as the spirit tells him or his wife will be killed.  O'Brien can't catch a break...

"The Assignment" has a lot going for it.  Miles episodes are generally satisfying and Rosalind Chao gets some good material as possessed Keiko, too.  We catch up with Rom, now working his way up the ranks in the engineering department.  We get a bit of a "Lower Decks" perspective as Rom joins his colleagues for a raktajino break.

The Pah-wraiths will figure prominently going forward, especially in the series finale.
