I never caught the beginning of this movie, but obviously Madie Levrington (Dyan Cannon) escapes from a New York state mental hospital where her husband Benjamin had her committed to avoid the trial of an expensive divorce. Madie hitches a ride back to California with Charles Callahan (Robert Blake), a debt-ridden trucker. He drives a GMC General, yellow maybe. Maybe they met in Kansas City or they stopped in Kansas City to pick up some cattle. They eventually fall in love. But Madie steals the truck, cattle and all, leaving Charles behind, to go to her home in California. Charles hitches a ride and eventually catches up with the truck. He climbs into the open-top cattle trailer. But he can't stop Madie from back there. "I hate cows!" he says. Madie reaches her husband's home. The prospects don't look good for Benjamin.
