This is the transitional season, where Harry Goz—and his character Capt. Murphy—died, and we got the replacement of Michael Goz as Capt. Tornado Shanks. The elder Goz appears in the first four episodes.
In "Tourist Season," Capt. Murphy spends $100,000 on ads to bring tourists to Sealab. Too bad all he's got to offer them is carnage in the dive pool and drinks laced with sodium amytal. The inspiration for the Soviet Realist packaging of this DVD set stems from "Red Dawn," in which Sealab's always-dictatorial leader goes whole hog, transforming the base into a Leninist "paradise." Hollywood gets the great idea to do a show based on the "real" Sealab and sends a narcissistic actor down to Sealab to do research in "Meet Beck Bristow." Always open to new experiences, the crew of Sealab swap their brains into robot bodies in "I, Robot, Really," becoming Freakbots who eventually get their own TV show.
Ice Station Zebra in the polar wastes is undergoing a trifling bout of cannibalism, and only rescue from Sealab can save them in "Frozen Dinner." That is, if the rescuers don't end up in the pot as well. Dr. Quinn and Debbie: always a hot item. That is, until they hit "Splitsville" and the other horndogs move in. "Tornado Shanks" introduces the newest member of the team, a self-appointed football coach who shows up out of nowhere and eventually assumes the captain's position. Earth is doomed in the path of a killer asteroid unless Sealab can use its new "Ashdtv" to deflect the rock.
When Dr. Quinn and Tornado Shanks have to substitute-teach Debbie Love's elementary-school class in "Chalkboard Jungle," they don't anticipate a deadly dodge-ball cannon. Sealab hosts a wedding in "Dearly Beloved Seed," but exactly who's getting married to what is the question. Surgery via shrunken humans in a sub: a familiar plot. But nothing goes as expected in "Craptastic Voyage." Every man and woman a sovereign state: that's the plot of "Let Them Eat Corn," when nukes begin to fly. A secret brotherhood of chosen ones: that's the "Neptunati," and they're endowed with the deadly Infinity Trident.
Extras include commentaries, two complete abandoned episodes, some promos and a mockingly political monologue by Stormy Waters.
