Canadian Coast Guard Ship Amundsen is a state-of-the-art research icebreaker. With 12 world-class labs, a multi-beam echo-sounder to map the ocean floor, and a moon-pool to launch an ROV under the arctic ice, she's a battle tested workhorse. Yet this mission will push her to the brink as she transports 24 scientists on a dangerous expedition into the treacherous Northwest Passage. Out in the cold water, deadly weather, rogue icebergs, and battered equipment threaten to put this mission into deep-freeze.
