When the planet Sarpeidon is about to be destroyed by its star Beta Niobe becoming a supernova, Kirk, Spock and McCoy beam down and find it evacuated except for Atoz, its librarian, tending with his replicas a collection of unusual discs, which play the planet's history and (to their surprise) allow their users to travel into the past trough the atavachron, a time machine, into the periods each was studying on disc, but they jump in unprepared. McCoy and Spock find themselves locked in a planetary ice age 5,000 years ago, where Spock reverts to the barbaric age of the Vulcans, hence touchy and intensely attracted to the political exilee Zarabeth, who enjoys getting company but tells them return is impossible. Kirk lands in a Cromwellian period, where he's arrested and suspected of witchcraft, but realizes the magistrate must be a time traveler like him, and learns not being prepared at molecular level he can return through the time portal, and in fact must do so and contact Spock and ...

When Spock tries to use his phaser to warm a boulder at the base of the ice cliff, it doesn't work - presumably because phasers didn't exist in that time period. But when he lays McCoy out in Zarabeth's cave and examines him, the doctor's medical tricorder seems to work just fine. See more »

a very good episode of season 3
8 September 2007 | by (Canada) – See all my reviews

The penultimate episode of Star Trek's third season is excellent and a highlight of the much maligned final season. Essentially, Spock, McCoy and Kirk beam down to Sarpeidon to find the planet's population completely missing except for the presence of a giant library and Mr. Atoz, the librarian. All 3 Trek characters soon accidentally walk into a time travel machine into different periods of Sarpeidon's past. Spock gives a convincing performance as an Ice Age Vulcan who falls in love for Zarabeth while Kirk reprises his unhappy experience with time travel--see the 'City on the Edge of Forever'--when he is accused of witchcraft and jailed before escaping and finding the doorway back in time to Sarpeidon's present. In the end, all 3 Trek characters are saved mere minutes before the Beta Niobe star around Sarpeidon goes supernova. The Enterprise warps away just as the star explodes.

Ironically, as William Shatner notes in his book "Star Trek Memories," this show was the source of some dispute since Leonard Nimoy noticed that no reason was given in Lisette's script for the reason why Spock was behaving in such an emotional way. Nimoy relayed his misgivings here directly to the show's executive producer, Fred Freiberger, that Vulcans weren't supposed to fall in love. (p.272) However, Freiberger reasoned, the ice age setting allowed Spock to experience emotions since this was a time when Vulcans still had not evolved into their completely logical present state. This was a great example of improvisation on Freiberger's part to save a script which was far above average for this particular episode. While Shatner notes that the decline in script quality for the third season hurt Spock artistically since his character was forced to bray like a donkey in "Plato's Stepchildren," play music with Hippies in "the Way to Eden" or sometimes display emotion, the script here was more believable. Spock's acting here was excellent as Freiberger candidly admitted to Shatner. (p.272) The only obvious plot hole is the fact that since both Spock and McCoy travelled thousands of years back in time, McCoy too should have reverted to a more primitive human state, not just Spock. But this is a forgivable error considering the poor quality of many other season 3 shows, the brilliant Spock/McCoy performance and the originality of this script. Who could have imagined that the present inhabitants of Sarpeidon would escape their doomed planet's fate by travelling into their past? This is certainly what we came to expect from the best of 'Classic Trek'--a genuinely inspired story.

Shatner, in 'Memories', named some of his best "unusual and high quality shows" of season 3 as The Enterprise Incident, Day of the Dove, Is there in Truth no Beauty, The Tholian Web, And the children Shall Lead and The Paradise Syndrome. (p.273) While my personal opinion is that 'And the children Shall Lead' is a very poor episode while 'Is there in Truth no Beauty' is problematic, "All Our Yesterdays" certainly belongs on the list of top season three Star Trek TOS films. I give a 9 out of 10 for 'All Our Yesterdays.'
