In a Michigan parking lot, a truck driver repeatedly rams a car in a seemingly random attack. On a remote road in Oklahoma, a group of motorcyclists get into an altercation with the driver of a pickup truck, who calls in a sibling and a neighbor for backup. On a busy Minnesota highway, a speeding car overshoots the onramp and careens into a semi causing a massive explosion. In Texas, a rapid response to an emergency call causes an officer to jump the gun at a railroad crossing.
