Tonight's film explores the animal community of a New England beaver pond. Few animals, other than man, alter their surroundings as much as the beaver. His dams create lakes and drown forests. As fast-flowing streams become still waters beavers provide homes and a living for many other creatures.
Spectacular photography takes us beneath the surface into a new world of hunters and hunted: hydras and waterfleas, nymphs of mayfly and dragonfly. It reveals the elaborate food chain that links them to the animals living on and around the water - both in summer's plenty and the harsh economy of winter. And then there are the beavers themselves, those industrious rodents upon whose efforts all ultimately depend. Narrated by John Hedges
