Eddie Wagner was a member an elite United States Army Special Forces unit, and was awarded a Medal of Honor for his service in the Vietnam War.
He was searching for his friend, and soon learn that he has died from cancer due to Agent Orange exposure.

He was soon spotted by the town's sheriff, Will Teasle who quickly drove him out of town.
He headed back into town immediately, to Teasle's dismay, who arrested him.
He was generally non-compliant with the officers at the station, and was beaten and harassed by a man named Art Galt which caused him to have flashbacks of his experiences during the Vietnam war- this caused him to snap.

He fought his way out of the station, stole a motorcycle, and was pursued off-road into the nearby mountains.
The deputies were eventually forced to search for him on foot, and he climbed down onto a steep cliff to elude capture.
Galt, who had spotted him from a helicopter, attempted to shoot him.
He dropped into a mass of trees, and cornered, threw a rock at the helicopter.
The helicopter pitched and Galt, the passenger, fell to his death.
Teasle, who did not see Galt's attempt to kill him, vowed to avenge his friend's death.

Teasle lead his deputies into the woods in an attempt to capture him.
The deputies were inexperienced and bickered particularly after learning over the radio about his combat experience and status as a war hero.

Eddie quickly disabled the small, disorganised team using guerrilla tactics and booby traps, severely wounding- but not killing- the deputies.
In the chaos, he isolated and confronted Teasle with a knife to the throat.
Teasle refused to give in.

Eddie was eventually cornered in a mine entrance.
The inexperienced guardsmen fire a rocket launcher at him, collapsing the mine, and assumed he was am dead.
He escaped into the tunnels of the mine with an improvised torch, and fought off rats.
He eventually found an exit, near a main road and hijacked a passing Army truck and returned to town, crashing it into a gas station, which effectively blocked the highway to anyone in pursuit.

Now armed with a machine gun, he effortlessly destroyed a surplus store and a sporting goods shop before making his way to the police station, where Teasle waited on the roof.
He, now surrounded by the police, raged about the horrors of war, and the difficulties he faced adapting to civilian life.
He wept as he recounted a particularly gruesome story about witnessing a friend's death.
He then turned himself in and was arrested.

I'd like to say this was an isolated event but actually he went on to display similar behaviour on 3 more occasions.
