Dr. Kimble wants to expose a defect in the bloodline of a kennel owner's dog, but the son and daughter-in-law threaten to stop him.

After escaping a police dragnet in Lincoln City, Nevada, Kimble comes upon Sister Veronica and her broken-down truck on a road in the desert hills. She convinces him to accompany her on her trip to Sacramento, despite his protests that he's heading in another direction.
