Jason Crockett is an ageing, grumpy, physically disabled millionaire who invites his family to his island estate for his birthday celebration.
Pickett Smith is a freelance photographer who is doing a pollution layout for an ecology magazine. Crockett hates nature, poisoning anything that crawls on his property.
On the night of his birthday, the frogs and other killer amphibians, birds, insects, and reptiles begin to pay Crockett back.
This was the first of many "eco-horror" films of the '70s, inspired by the surprise box office success of Willard (1971).
The mansion used for the Crockett family home is known as the Wesley House and is located in Point Washington, Florida.
Many of the 500 frogs and 100 giant South American toads purchased for use in the film escaped during production.
