"Assignment: Earth" is the twenty-sixth and final episode of the second season of the American science fiction television series Star Trek. Written by Art Wallace (based on a story by Wallace and Gene Roddenberry) and directed by Marc Daniels, it was first broadcast on 29 March 1968.[1]
In the episode, engaged in "historical research", the USS Enterprise travels back through time to 1968 Earth, where they encounter an interstellar agent planning to intervene in 20th-century events. Kirk and Spock are uncertain of his motives.
It was originally written as a standalone half-hour television series; when no network chose to order a pilot, the script was reworked to fit into Star Trek as a backdoor pilot for the proposed Assignment: Earth series.[2] The spin-off series was never produced.
This was Teri Garr's first significant TV role.[3]
