When the Enterprise is assigned to observe Earth's history in 1968, suddenly it intercepts a transporter beam which originates at least a thousand light-years from Earth, bringing aboard a humanoid alien 'agent Gary Seven' holding a black cat called Isis, who warns them to step back and let him go to accomplish his mission to save Earth; initially phaser-struck down, he manages to beam himself away, actually on a mission to prevent a nuclear rocket being launched at McKinley base because earth is socio-politically not ready for its technological progress. He assumes a classified identity to override a powerful computer, and mistakes the wrong girl, Miss Lincoln, for another agent; the computer reports both other agents he seeks are deceased in an accident. Meanwhile Kirk and Spock beam down to investigate if the alien isn't hostile, realizing the risk of changing their own past. When they get on his trail, the girl sees Spock's ears, calls the police and Seven gets away; they must ... Written by KGF Vissers

Past, Present, and Future
29 March 2014 | by (Buffalo, New York) – See all my reviews

One of the best Star Trek episodes was this one where the Enterprise has troubles reconciling past, present, and future when it interferes with a transporter beam that takes a man from the future on the ship and the whole ship and crew are beamed to 1968.

The man from the future is Robert Lansing, code name Gary Seven and he's there to find what happened to a pair of agents from his time which is a thousand years ahead of the Enterprise future. He has a mission and he's on a deadline having to do with an orbiting satellite with an array of impressive nuclear weapons.

The dilemma for William Shatner and Leonard Nimoy and for the whole Enterprise crew is what to do. They follow Lansing down, but of course aren't sure how their actions might change history. The not knowing makes this a most tense episode.

Also Teri Garr gives a wonderful performance as a young woman who'd been hired by the two missing agents whom we learn were killed as a secretary. She's a bright but somewhat spacy girl who isn't quite sure what she's caught up in. Every scene she's in, Teri Garr steals.

Another thought provoking episode from Star Trek prime.
