Kai Opaka, the spiritual leader of the Bajorans announces a visit to DS9. She doesn't say much, but makes it implicitly clear she's interested in the wormhole. Sisko, Bashir, Kira take a runabout to show her the wormhole and pass through it to the other side. They receive a strange distress call coming from an unknown source. Sisko wants to return home, but Opaka tells him they should not take notice of her. The signal leads to a mysterious satellite network, which releases an energy burst, disabling the runabout. They make a violent crash-down on a moon, where Opaka dies almost instantly. It isn't long before the surviving 3 are picked up by a group of unfriendly locals, the Ennis. They say they are put as prisoners on the moon after a long war with the Nol-Ennis, a war ehich is continued on the moon. When the Nol attack, something strange happens. Written by Arnoud Tiele (

Did You Know?


The original concept involved a group of Humans and Cardassians, although this was changed to the Ennis and the Nol-Ennis so it would not look like the main characters had chosen sides. See more »


The nacelle on the ground after the Yangtze Kiang crashed, does not correspond with the style the Runabouts have, but rather the nacelle from a Type-6 shuttlecraft. See more »


[Major Kira has been ranting about the poor defense measures of the Ennis]
Shel-la: [quietly] We used to defend ourselves better, Major - safety perimeters, counterattacks, preemptive strikes... And then we realized... that it was all pointless. When you cease to fear death, the rules of war change. You'll understand as the years begin to pass, Major.

Planet of the Jerks!
14 December 2014 | by (Bradenton, Florida) – See all my reviews

The Bajoran holy woman, Kai Opaka, unexpectedly shows up on Deep Space 9. Even more unexpectedly, she longs to be taken through the wormhole. However, after the runabout with Sisko, Kira, Dr. Bashir and Kai Opaka nears a moon, the planet's defense systems knocks down their craft and the Kai is killed. Once on the surface of this moon, they find a hellish and stupid group who are CONSTANTLY at war with their enemies. Now here's the rub...soon Kai Opaka comes back to life and Dr. Bashir realizes that their's some artificial organism that deliberately keeps everyone on the moon alive forever...and this war seems to be going on forever because these folks are stupid idiots. What's next?

This episode actually seems very similar to an episode from the old "Star Trek", "Day of the Dove"--except that "Battle Lines" is much better and doesn't suffer from a silly and unrealistic ending. Well worth seeing.
