Season 1

When the annual Sealift enters the Arctic, it faces the worst ice in years. Global warming has dumped tonnes of glacial debris into the shipping lanes trapping the Sedna Desgagnés.

After two days adrift and alone in the Arctic, Captain Duplain's crew is finally rescued from the ice when a Coast Guard icebreaker returns to the Sedna and leads the ship through the ice pack.

Captain Duplain's crew is short-handed after an unexpected departure. Equipment breakdowns and high winds threaten the Sedna's delivery to Cape Dorset. And Arctic isolation forces a cadet to make a tough decision.

The Sedna reloads in Montreal and welcomes a new first mate aboard. 25-year-old Guillaume Rosso needs to prove to Captain Duplain that he deserves to be second-in-command.

The crew of the Sedna scrambles to control a flood below decks that is threatening to damage the cargo. The Taiga gets pounded by an open coastline and has to complete a daring ship-to-ship transfer to ensure cargo delivery to some remote communities.

Captain Duplain and the crew of the Sedna must navigate the notorious Simpson Strait - a shallow passage that starts where Sir John Franklin's failed Arctic expedition ended.

Winter is creeping into the Arctic and closing down the Sealift's shipping lanes. The Sedna gets a two Icebreaker escort to escape the High Arctic and deliver the first craft brewery to Baffin Island.
