Brothers Ernie and Lars Smuntz find themselves inside a old mansion their father left them. The brothers decide to hold an auction for the mansion, and as they try to update and clean it up, they also find themselves trying to get rid of a crafty mouse. No matter what they do, from mouse traps to CatZilla, from Caesar the Exterminator to guns, they can't stop the mouse. Running out of money, Ernie decides to sell their father's string factory, though Lars knows he's making a B-I-G mistake. Their father's personal quote was "A world without string...is chaos."
