Flash The King

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.

All these stories run at the same time -- affecting the currents that, in turn, affect all the other stories. That's Chaos Theory

Only the author of Book of the Monk, Okay, Fine, and Space Sex could even try making sense out of this sort of chaos.
