Leaving the dusty outskirts of Los Angeles behind, two travelers cross the desert on the predecessors of Harley-Davidsons, setting out on a long ride toward the heart of the country. This adventure, directed by Dennis Hopper, traces a quest for spiritual truth amid the order that has become trapped along the edges of the highways. Vast landscapes, endless roads, and echoes of a counterculture, combined with the rumble of the engines, reveal the fragile face of the American Dream.
