A careening tanker truck rips through the fence of a wild animal park, unleashing an untamed force of nature on an unsuspecting community. 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. Carol Lynley, who fought her way through an upside-down luxury liner in THE POSEIDON ADVENTURE, returns to the disaster-pic genre as a dedicated veterinarian thrust into the forefront of the people vs. beasts panic. Also in the cast: Philip Michael Thomas before he shot to fame in MIAMI VICE.
