Don Johnson and his dog communicate telepathically as they scavenge the ruins of post apocalyptic America circa 2024. Based on a Harlan Ellison novella, the second half of the film tails Johnson, sans pooch, as he follows lust interest Suzanne Benton into a subterranean community, (run by Jason Robards) that is trying to preserve middle class American values. In the end, a dog is man's best friend, and his woman, the dog's dinner.
