In 1965, three young Englishmen set off in their Land Rover to catch a ship to South America with the plan to drive the Pan American highway to the United States, where they hope to find jobs. While traversing South and Central America, Dave, Len, and Charlie face down bandits, encounter escaped Nazis, go wild boar hunting with a Hungarian Count, stay with missionaries, bribe border guards and hitch a ride on a German freighter from Colombia to Panama. A change in U.S immigration laws leaves them stranded in Mexico. Undeterred, they cross into the U.S. and join a group of illegal migrant workers in the orange groves of Southern California, and the adventure is just beginning.
