Carpenter Street (Star Trek: Enterprise)

"Carpenter Street" is the 63rd episode of the American science fiction television series Star Trek: Enterprise, the eleventh episode of season three. It first aired on November 26, 2003, on UPN in the United States. It was written by executive producers Rick Berman and Brannon Braga and directed by Mike Vejar.

Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In season three, the ship enters the Delphic Expanse to search for a Xindi super weapon in response to an attack on Earth. In this episode, Captain Jonathan Archer (Scott Bakula) and Sub-commander T'Pol (Jolene Blalock) travel back to early 21st-century Earth to find a group of Xindi-Reptilians seeking to wipe out the human race by using a biological agent.

The Los Angeles production of the episode used several different methods to represent 21st century Detroit, including exterior shots around Los Angeles, exterior sets at the Lacy Street Production Center, and shots at the downtown New York standing sets at Paramount studios. The guest cast featured Matt Winston returning as Temporal Agent Daniels, and Jeffrey Dean Morgan as a Xindi-Reptilian. It had the lowest number of viewers of season three at that point according to the Nielsen ratings, a decline attributed to pre-Thanksgiving travel. Critical response was mostly negative, with criticism directed at the plot.
