Survival Is an Ugly Beast

S3, E9: Rob has most of his Prepper boxes checked: enough food to feed his family for two years, self-made bullets and a stockpile of weapons. In order to protect his family from Doomsday marauders, he is devising the ultimate booby-trap system. With the help of a neighbor, Rob is securing his Texas property's perimeter with an elaborate system of alarms, traps and defense mechanisms. But when an unexpected tornado hits, Rob goes into instant Prepper mode and booby-trap plans must be put on hold.
