Synopsis by Hal Erickson
While spacewalking, Crichton (Ben Browder) is sucked into a small wormhole, ending up on what seems to be a floating iceberg occupied by an oddly garbed old man (John Bach). It turns out that the stranger, whom Crichton joshingly nicknames "Einstein," is from a race known as the Ancients, who centuries before had discovered that the universe was connected by a sort of "wormhole highway" and had dedicated themselves to keep the millions of realms thus connected safe from harm. Crichton is told that his own accumulated wormhole knowledge has the potential to disrupt or destroy all the alternate realities in space -- and thus, Einstein has no choice but to execute him. Several former Farscape regulars make cameo appearances via highlights from earlier episodes.
