Young scientists embark on a journey across the Pacific to explore the mysteries of the ocean depths and discover previously unknown life forms. Their research could help protect the ocean from mineral exploitation. Will their enthusiasm overcome commercial interests? Life on the ship is not only about science but also about getting to know one another and reflecting on humanity’s place in the world. The deep-sea ecosystems, the last unexplored spaces on Earth, reveal the fragility of nature and raise questions about our care for the planet and the future of endangered species. How much do we love our planet? Will we regret losing so many species of flora and fauna forever? The film’s melancholic tone encourages reflection, and observing scientists operating the Isis robot in the dark depths becomes a metaphor for exploring the human subconscious.
