This bleak post-apocalyptic science fiction actioner substitutes a plague instead of a bomb as the reason for civilization's demise but the result is the same -- grizzly motorcycle gangs with a ton of gasoline to burn. In City Limits the older generation has been wiped out by the plague, and the younger generation lives in a state of anarchy in a world controlled by biker gangs. The gangs live by rules discovered in pre-apocalyptic comic books. Two rival biker gangs, the Clippers and the DAs, have taken to dividing up a city amongst themselves and live under a fragile truce. Utilizing a comic-strip version of medieval times, a code has been established for violations of the pact between the gangs -- competitive jousting or acts of reciprocal retaliation. When a person dies, like a post-Holocaust Viking funeral, he is cremated along with his motorcycle. But this shaky peace between the bike gangs is threatened when the fascistic Sunya Corporation attempts to take over the city with the cooperation of the DA bike gang.
