Manny, Diego, and Sid embark upon another adventure after their continent is set adrift. Using an iceberg as a ship, they encounter sea creatures and battle pirates as they explore a new world.

Débâcle (a french term referring to spring ice breakups) draws its inspiration from the shifting courses of the St-Lawrence river during wintertime. Through a search for the vast ice patch which usually clings to the Quebec North Shore coastline during the colder months, Débâcle bears witness to climate change and the fragility of our coastal territory.
