This is a combination message movie and horror film, punctuated with gruesome animal attacks. The story starts with dangerous PCBs contaminating a German city's water supply. While the toxins might have a negative impact on the health of the human population, it's impact on the animals in the zoo is immediate: it drives the animals in the zoo off their feed and a further accident gets them into the streets. The chief zoo keeper, a female reporter and a police inspector team up to try to get the fearsome beasts under control and protect the city's population. Mangled bodies and some horrible deaths are strewn across the screen before the disaster has ended.
