Renowned paleontologist Kirk Johnson embarks on an epic adventure through time at the polar extremes of the planet. Following a trail of fossils found in all the wrong places - beech trees in Antarctica, redwoods and hippo-like mammals in the Arctic - NOVA uncovers the bizarre history of the poles, from miles-thick ice sheets to warm polar forests teeming with life.
