The Enterprise responds to a distress call from the planet Scalos, but when Kirk and a landing party beam down to the planet they find no living beings. It turns out that the Scalosians live at a much higher rate of acceleration, rendering them invisible to the human eye. One of the Scalosians, the beautiful and seductive Deela, accelerates Kirk so they can interact, where she tells him he cannot return to his normal life. For the crew, Kirk has virtually disappeared before their eyes. The Scalosians want to turn the Enterprise into a cryogenic storage facility for the crew. Kirk learns that at his current state of acceleration, they are subject to cellular degeneration and rapid aging should they suffer the slightest cut. He leaves a message for the crew but it is left to Mr. Spock to find a way to decipher it. Written by garykmcd

When Kirk first meets Deela and fires his phaser at her on the bridge, the turbolift doors, which should be closed when not in use, are inexplicably open for quite some time. (If this were due to someone in normal-time entering or leaving the compartment, we would be able to see them doing so.) See more »

Don't drink the Scalosian water before bed.
24 October 2006 | by copper1963See all my reviews

Star Trek always had what I called the "Macy's Parade" approach to working within a budget--especially in season three. Matte paintings, props,sets, visual effects shots, all were fair game for the producers to utilize, repaint and reconfigure to save money. They must have thought viewers had short memories. Not "Trek" fans. With that said, this episode did a great job of pulling off a lot with the barest of essentials. The Enterprise's landing party transports down to the planet's surface to find a deserted city. This is odd because they were recently sent a distress signal by the inhabitants of this world. A crew member, planet-side, stupidly, takes a drink from a cascading water fountain and disappears. Kirk and the others hear (but don't see) buzzing insects. They are, needless to say, a little perplexed by this turn of events. They scurry back to the ship. On the bridge, Kirk drinks a cup of coffee and he too disappears. The Scalosians, you see, have been able to accelerate themselves into a state of hyper-space. Their motives are not good--it's a trap. I wonder if one of the ideas for this wacky story, may have sprung from a movie titled "The Time Travelers," and it's low-budget remake, "Journey to the Center of Time." Something to keep in mind when you watch this episode, one of the best from Star Trek's final season. Space trivia alert: Kathie Browne, Kirk's love interest in this story and female leader of the Scalosians, was married to the "Night Stalker" himself, Darren McGavin. Sadly, Ms.Browne and her husband passed away in the last few years. But their cult status as icons of 60's television remains intact.
