This time, The Stranger mysteriously appears out of the heat waves of the desert and rides into the lawless, sin-ridden town of Lago. After making a name for himself with a string of blazing gun battles, The Stranger is hired by the townspeople to provide protection from three ruthless gunmen just out of jail.

Michael Boll, an ambitious young businessman who seems to have everything, befriends Alex, the mysterious drifter, who takes him for a walk on the wild side and on a run for his life.

A wild cross-country trip with a political revolutionary, this satire of American radicalism moves from psychedelic 60s Greenwich Village to New Age 80s California.
