The Riverboat Gamblers have been cloned and sent to the bottom of the ocean in chains. They escape and journey to defeat their clones, encountering mermaids, trash monters, a claymation octopus, and evil robot scientists. "Don't Bury Me...I'm Still Not Dead" is a fun B-movie sci-fi romp full of lasers, creatures and other eye candy.
