An otter family arrives at Yellowstone Lake in the winter. Here they can fish in the holes kept open by the underwater geysers. But every time they catch something, a coyote is watching and waiting. One otter dives under the ice to hide its fish from the coyote. The coyote can’t see the otter because of the thick cover of snow. But he can hear him and dives into the snow to find him. The otter emerges without the fish. He’s stashed it somewhere under the snow. But where? The coyote digs a deep hole in the snow and finds a huge Yellowstone cutthroat trout. With the help otters' help, a wily coyote can catch fish too.
