A British-Cavadian team of scientists, including BBC presenter Chris Packham, arrives at Greenland's western coast to study the country's largest glacier and the icebergs it gives birth to, a spectacular process, yet never extensively studied. A former explosives expert takes the lead in most physically dangerous operations, as to plant scientific recording equipment at perilously unstable and inaccessible spots. Combined with observations from a boat on and dangerously close to the surrounding sea, they find the part played by melting water forming lakes on the glacier top, canals to the rock underground and maritime circulation.

The British-Canadian scientists party boards a ship to follow a mega iceberg broken off from a Greenland glacier. It lives two years, so who so long and what gets to it eventually? Spectacular but also precarious is the surprisingly numerous population of polar pears who swim to it and stay on the iceberg quite a while during the absence of continuous ice on Artcic land.
