Peter and Chloe, a young married couple from New York, decide on impulse to take a belated honeymoon on-board a research vessel en route to the icy wastes of Antarctica. Not long into the journey, Chloe begins to feel neglected and betrayed by Peter, who is focused on gathering information for an article he plans to publish on their return about the work of one of their fellow passengers, the whale biologist Roger Payne.
