Louise is quite emotional now that she's pregnant. Her finance, McCann, is working on a history of the Psychedelic Sixties. When they are fighting, they write vitriolic letters berating each other on the Internet.
McCann invites a semi-fried hippie Light Show gum to come back to Los Angeles to put on a light show.
Meanwhile in Viet Nam:
Ahn Phong's husband was an ARVN pilot killed as a traitor after the Viet Cong won the war. Alan has been forced into being a prostitute to earn money for her escape passage to Hong Kong with Black Lam, a river pirate. Ahn is in an opium haze when Black Lam rescues her from the brothel, after murdering a high government official who is renting her -- the start of a long and intricate chase through the Saigon slums -- own the Saigon River to the Mekong Delta.
Intercut with:
The Hippie Light Show trying to get to LA. He picks up a waitress at a truck stop. Through snow banks and flat tires, they progress, with her little son, Timmy, and his pet turtle, toward the blue Pacific.
