When Farmer Mason discovers that the rats living in his barn and stealing his wheat have evolved intelligence, he turns to an extermination company to deal with the problem. They install several laser turrets, which starts a full-on war, but the rodents take the first round by destroying the equipment. Mason then upgrades, purchasing a literal rat-killing scorpion machine. Its excessively violent methods make Mason uneasy however, and during the final battle within the barn, Mason has a change of heart, destroying the scorpion before it can wipe out the rest of the rats. The act seals a new truce between Mason and the rats, who offer Mason a tiny flask of the moonshine they’ve been brewing with his wheat.
