The only two-part episode during Star Trek’s Original Series run, “The Menagerie” aired on November 17th (part one) and November 24th (part two) 1966. This episode allowed the Star Trek producers to ease the pressure and cost of putting out a new episode every week by reusing footage from the unaired pilot (“The Cage”) and splicing it in with some newly shot scenes. It also allowed Roddenberry to work around the network and make his original vision of the series still part of the overall canon.
Synopsis (from IMDB):
Spock kidnaps the crippled Capt. Pike, hijacks the Enterprise and then surrenders for court martial.
It might also help to know the synopsis for the original pilot, “The Cage,” from which the scenes were spliced into for the two-part episode (also from IMDB):
Capt. Pike is held prisoner and tested by aliens who have the power to project incredibly lifelike illusions.
