T'Pol tells Archer and Trip a story about her great-grandmother T'Mir and three other Vulcans who made first contact with humans after crash landing in a small Pennsylvania town in the 1950s. T'Pol's story shocks Archer and Trip because her account is much earlier and very different from what history books reported.

"Creek" relates a time in 1957 when Vulcans secretly visited Earth. The episode's flashbacks focus on T'Pol's great-grandmother, played by Blalock. It began production on July 26, on location near San Bernardino, California, for two days. Blalock and the guest cast returned to the Paramount lot that Friday to begin shooting on sets depicting the titular Pennsylvania town, as well as the bridge of a 20th-century Vulcan ship.
