Starting on New Year's Day, Britain is in the grip of winter. Time-lapses show a magical country shrouded in frost and mist swirling in hollows. Water becomes the enemy as it freezes, and the wildlife must cope. Red squirrels resort to subterfuge, and kites track a farmer ploughing to get at the worms beneath the frost. As winter fades, adders bask in the sun and the woodland floor erupts with snowdrops. On a lake in Wiltshire, new hope is captured in the evocative dance of the great crested grebe.
