When the Enterprise attempts to stop an unidentified vessel on a collision course with the Beta Niobe nova, the ship accidentally passes into an alternate dimension where time flows in the opposite direction. The crew of the Enterprise rapidly begins to grow younger in age and soon becomes unable to man the consoles. Written by The TV Archaeologist

Did You Know?


Robert April's Starfleet dress uniform was based on similar costumes used in the original Star Trek series beginning with Star Trek: The Original Series: Court Martial (1967). See more »


Kirk mentions that there are 430 people aboard the Enterprise, as in Star Trek: The Original Series. Under the economy of drawing the animated series (or hiring extras in the original), the viewer rarely, if ever, has a sense that there are more than 15 or 20 people on board. See more »


Mr. Spock: Captain, the flower is not the only thing on board that is growing younger.
Capt. Kirk: Explain, Spock.
Mr. Spock: Ship's chronometers are also running backward. The flow of time is reversed in this universe. The longer we stay here, the younger we will become.

An Interesting Conclusion
2 April 2017 | by HitchcocSee all my reviews

I don't know if there is any science that supports what happened here, but there are good intentions all around and a solid message. By trying to do good, the Enterprise cause some serious damage and has to find a way out of it. An alien vessel is heading into a nova and they try to stop it, not realizing that they were on a necessary trip. We have a preposterous solution, but every episode of this animated series was preposterous.
