When things start going missing on Sealab, fingers start to point and tempers start to flare. It'll be up to Murphy and his cadre of Martian Knights to quell the chaos. Or, more accurately, to exacerbate the existing chaos into something much more chaotic. But at the end there might be cake.
In a fevered spurt of conspicuous consumption, Murphy runs up a hundred grand in credit card bills. And let's face it: He just doesn't have that kind of money. So he sends his unwilling crew in search of sunken treasure. Sharks? Sure. Lack of oxygen? You bet. And hey, isn't that dynamite over there? Well, I'll be darn.
When the nuclear submarine "Aquarius" crashes into Sea Mount, Captain Murphy and the crew of Sealab must prevent its reactor from overheating and exposing the ocean floor to deadly radiation. They'll need all the courage and determination they can muster to prevent an environmental catastrophe.
Legend of Baggy Pants
Murphy's golf game is cut short by a lack of balls. In his frantic search for the pro shop, he encounters Monster-Hesh, snotty telephone operators, Dolphin Boy and the perfidious Eggers. Of course, none of that matters when you're blowing the foam off a couple of cold ones down at The Idiot. "Hey! Is that my hat?!"
Swimming in Oblivion
