Slacker siblings Marion and Jarmon Mugg discover that a mysterious beast is feeding on the frustrated tenants who inhabit their dilapidated brownstone apartment complex, and decide to take matters in to their own hands instead of calling pest control. Ever since their mother died and left them the building two years ago, Marion and Jarmon have sat and done nothing as it fell into a hazardous state of disrepair. As the tenants start to flee in droves, the brothers come to the terrifying realization that they have a monster problem on their hands. Despite being quite possibly the two most ill-equipped people in the entire world to do battle with the burrowing cryptozooid, Marion and Jarmon slap together a pair of ramshackle protective outfits, purchase a pair of shovels, and descend into the basement to terminate with extreme prejudice.
