The episode begins with Jadzia Dax asking several of the crew members for a strange favor--to borrow their bodies for a short amount of time! It's part of an odd Trill ceremony where the old hosts' spirits are brought back through some mumbo jumbo--and the spirits will inhabit their temporary hosts. They agree and the results vary quite a bit. One is an evil murderer and he only inhabits Sisko briefly (because he's so nasty), my favorite is a female host who inhabits Quark (it's pretty funny) and then there is Curzon Dax--who turns out to be quite the character.
The other plot (and there are almost always two in every episode) involves Nog working hard to get into a special training program for folks wanting to get into Starfleet. While a minor plot compared to the one above, it was quite touching seeing him and his father-- especially with Rom being so very proud of his boy.
All in all a very inconsequential episode since nothing earth-shattering occurs and it seems like filler, BUT it's also quite fun and great when it comes to character development. Well worth seeing.
