The second episode of the short-lived NBC series The Fantastic Journey premieres. Katie Saylor joins the cast as Liana, a character not included in the original series outline who helps the few holdovers from the pilot episode. 
A woman named Rhea leads Scott, Varian and Fred to the city of Atlantium, where the three travelers are told that Professor Jordan and the female members of his expedition have returned to their own time, leaving Scott to fend for himself. Fred and Varian promise to look after Scott, but the Atlanteans have other plans for him: their disembodied leader, the Source, has chosen Scott as his new host body. Liana, a woman whose father was from Atlantis and whose mother was from another solar system, leads a resistance movement against the Source’s hunger for power; she warns Varian of the Source’s plans for Scott. Varian and Paul demand to see Scott after the Atlanteans take the boy under their wing, but there’s something wrong with Scott when he is returned. Varian eventually figures out that the Source has created a clone of Scott to keep the boy’s friends distracted while the real Scott is prepared for his new destiny. Liana helps Varian and Fred fight their way through Atlantium to rescue Scott, but the only guaranteed way home is through the use of the Source’s power; the man from the future and his 20th century friends are now stranded.
