Follow four teams of car mechanics in Appalachia, as they each build a rat rod over three weeks and compete against each other in the first rumble, which is held at an undisclosed location in North Carolina. The rat-rod movement emerged after World War II when prewar cars were salvaged from junkyards for a couple of dollars and modified to be street ready -- far from the flashy and expensive hot rods at car shows today. But deep in Appalachia, they still like their rides with a little rust. JR Drake, Ricky Bobby, Rooster McGee and Greg Porter fish old Model Ts out of creeks, wander onto private property and chop up modern day minivans in order to build the most outlaw rides possible. These mechanical savants cobble together these old abandoned car bodies and mash them with parts off of anything and everything. Their teams work without sleep all in the hopes of winning the first rumble -- and becoming the top dog on legendary Rebel Road
