On January 2, 1995, Deep Space Nine belatedly rang in the New Year with part one of this two-part adventure. A transporter accident sends Sisko, Bashir, and Dax hurtling back to 21st Century San Francisco. Upon their arrival, they are forced to confront the plight of the city's homeless and to avoid contact with those unfortunates, lest they alter events that could profoundly and dangerously change the course of the Future. Part one of "Past Tense" was scripted by Robert Hewitt Wolfe from a story by Wolfe and Ira Steven Behr. ~ Hal Erickson, All Movie Guide
