The director Félix Lamarche questions our relationship with the St. Lawrence River during the winter. Aboard the Amundsen, a Canadian coast guard icebreaker, we follow passionate scientists who explore the mysteries of an inaccessible nature. Combining the landscapes of the ice floe and the invisible movements of underwater life, the film takes us on a documentary journey to the heart of this still little known river.
