Archer receives a surprise visit from Daniels, the mysterious time traveling operative who has aided him in the past. Daniels tells Archer that three Xindi-Reptilians have somehow traveled back in time 150 years to Detroit, Michigan. He wants to send Archer and T'Pol back in time to investigate. He also gives Archer temporal tags to bring back anything that doesn't belong in the 21st century. After disguising them in clothing from the proper time period, Archer and T'Pol successfully travel 150 years in the past, arriving at night on a Detroit City street.
