Bison, zebras, camels, antelopes and ostriches stampede down the highway. Elephants and rhinos crush cars. A panther terrorizes a family's pet dog. A tiger turns a fleeing bystander into helpless prey. A lion prowls near a home. A local amusement park becomes an arena for a vicious bear-vs.-tiger clash. As park rangers and local cops scramble to recapture the escaped animals, two trigger-happy good ol' boys decide to go big-game hunting.
