An amateur scientist finds a portal into alternate universes. It’s not just time travel: Everything you know of our world (save basic scientific principles) is up for transmogrification. He and three friends get caught up in the vortex the first time he turns it on, propelling them on an adventure into other worlds--but all they want to do is get home. Includes all 10 episodes from the 1995 season and all 13 from the 1996 season. Commentary by co-creators Tracy Torme and Robert Weiss, plus a new making-of featurette.
