Newfoundland: A research team from a nearby university has established a research station in a small harbor to investigate the mysterious phenomenon of the recently frequent bioluminescence. By chance, young marine biologist Vivienne nets a creature unknown to science: a type of fish, but Vivienne immediately feels an emotional connection to the being, which exhibits female characteristics and is clearly capable of strong feelings. As Vivienne's superiors attempt to exploit the incredible discovery for their own purposes, the creature's life is threatened, and Vivienne must make a decision.
