The Polar Region (S5E15)

When the Enterprise responds to a distress signal sent by an ugly starship, they decide to rendezvous with it in a dark planetarium. But after their away team returns acting strangely they start a firefight in ten-forward, where no glass table is safe. How far will O'brien go to avoid dinner with Keiko? How much prep is involved in trying a new orbit? Can a transporter help with "going clear"? It's the episode where we open some fresh cards!
