The Voyagers are separated: Bogg is with Lawrence of Arabia, while Jeff is stranded in the 1800's with Thomas Alva Edison. When Jeffrey awakes after a rough landing, he learns that Edison has dismantled the Omni and not invented the light bulb. A piece of thread is the answer to the incandescent light but Edison can't figure out the Omni. He rebuilds the strange device and Jeff returns to Arabia, unknowingly saving Bogg and Lawrence as they are being led to their deaths. A chase through the catacombs leads Lawrence, Medina, and the Voyagers to safety and Lawrence is reunited with his people. The Voyagers return to Menlo Park to see the electric light used outdoors for the first time.
