In 2041, Whitney, a young biracial woman, studies a volcano weakened by climate change in the cold Yukon, while the climate crisis has brought a flood of Caribbean refugees to Canada. She returns to Montreal to retrieve a scientific sample from a Caribbean island engulfed by the ocean. The theft of the sample and the supernatural appearance of her Caribbean ancestors resurface her repressed questions about her origins and plunge her into the heart of Montreal's Caribbean community, ultimately leading her to follow in the footsteps of her unknown biological father.
