This is a documentary about the fragile and complex marine ecosystem in the Bay of Fundy. The film traces relationships within the food chain - from tiny plankton to birds and seals and finally to whales and humans. The film is a plea for careful management of our ocean resource and was first telecast as part of CBC's Nature of Things series.
