Documentary following British wildlife through the seasons, beginning on New Year's Day, with the landscape in the grip of winter. Time-lapse photography shows a magical country shrouded in frost and swirling mist, while water becomes the enemy as the creatures must cope with ice. Red squirrels resort to subterfuge, kites track a farmer's plough to get at the worms beneath the frost, and as winter fades adders bask in the sun and the woodland floor erupts with snowdrops.
