Please feel free to comment on my review.

I enjoyed this ‘Star Trek’ episode very much, although I wouldn’t consider a favourite of mine. It is a pretty mind-boggling episode where one Starfleet crewmember gets taken over by these alien lights.

The Enterprise is joined by Jan Shutan as Lt. Mira Romaine. She’s on the Enterprise to accompany the crew on a special mission to Memory Alpha, a planetoid full of Federation computer databases.

This episode also sees Scotty showing a more romantic side in ‘Star Trek’ as he clearly fancies Mira Romaine. It was nice to see a romance for Scotty for a change and Mira seems quite taken with him.

I found this a better romance story for Scotty compared to ‘Who Mourns For Adonais?’. Scotty clearly cares for Mira, especially when she gets in trouble and becomes affected by the peculiar alien lights.

The Enterprise encounters these alien lights in space on the way to Memory Alpha. The lights affect everyone’s nervous systems, particularly when Kirk can’t speak and he loses his voice on the bridge.

But Mira is the only one who seems to have passed out from the lights’ attack on the Enterprise ship. Mira gets edgy afterwards when she’s ordered to go to sick bay to get a check-up by Dr. McCoy.

Mira is anxious about being sent back home to Starfleet since this happens to be her first mission. She experiences strange moments when he sees visions of the future via the alien lights from space.

They soon come to Memory Alpha to discover that it has been attacked by the alien lights. Kirk, Spock, Bones and Scotty beam over to investigate and discover the personnel on board are all dead.

They then find one crewmember who is speaking in a strange inaudible voice and her skin colour changes green and red. The crewmember eventually dies and Kirk and the others are left in the dark.

Mira eventually joins Kirk and the others on Memory Alpha to find that the crew are all dead. Mira warns Kirk that they must get back to the Enterprise and get away, since the lights are coming back.

It soon transpires according to Spock, that the strange lights in space contain life-units inside them. This means that there is a community of life-forms inside the alien cloud of lights that follows them.

The Enterprise tries to make contact with the alien cloud of lights, before they eventually fire their phasers into it. Mira gets injured when the phasers fires into the cloud, as he’s somehow a part of it.

Eventually, Mira joins Kirk, Spock, Bones and Scotty for a briefing to determine what is going on. It turns out that the alien life-units of the cloud are becoming a part of Mira inside of her brain waves.

Time runs out as Kirk and the others decide to free Mira from her influence of the alien cloud by putting her into a pressure chamber on bard the Enterprise. The lights soon take over Mira entirely.

It was pretty tense when the Lights of Zetar, that’s what they are by the way, speak through Mira and she has a deeper voice. The Zetar aliens want Mira’s body and tell everyone that they will all die.

I liked it that Scotty had faith in Mira as well as love when they were helping to free her of the Zetar alien’s influence by putting her in the pressure chamber. It gets tense but she comes out of it alright.

‘The Lights of Zetar’ is not one of my most standout favourite episodes from the ‘Star Trek’ series. But I did enjoy this one and it was a nice change for Scotty to have a little romance with Mira in this.

The DVD special features for this episode are as follows. On Disc 5 of both the original and re-mastered DVDs of ‘Star Trek: The Original Series – Season 3’, there is a preview trailer for this episode.

    I like it when James Doohan as Scotty gets a chance to fall in love with a beautiful woman and he has good tastes, especially in Mira. Such a shame that these romances in ‘Star Trek’ don’t last long beyond one episode! 😀

    Tim. 🙂
