Classic cars move people in unexpected ways: in Nashville, a couple of neighbors who didn't speak, until a car spoke for them; in San Francisco, a convertible Chevelle bonded a clothing tycoon and an electrician to fight Asian hate.

In the Bay Area and Houston, a love of classic cars leads to some unlikely friendships; a bond between an 80-year-old truck driver from Alabama and a young executive; a '79 Camaro that built a lifelong relationship between a former NFL linebacker and a cop; and a love of classics cars that grew into a "family affair."
