Constructing a new spaceship based on ancient Bajoran designs, Sisko embarks upon a journey to Cardassia, with his son Jake along for the ride. The purpose of this journey is to prove the veracity of a 600-year-old legend, if the two men can live long enough to complete their mission. Meanwhile, Bashir is reacquainted with Dr. Elizabeth Lense (Bari Hochwald), an old hearthrob from his Starfleet Medical School days. Scripted by Rene Echevarria from a story by Hilary J. Bader, "Explorers" first aired on May 8, 1995. ~ Hal Erickson, All Movie Guide
