Kostas, a 75-year-old diver, makes his living raising toxic shipwrecks from a polluted seabed. As the community around him dreams of environmental renewal, an ancient Greek underworld myth resurfaces through a doomed vessel he vows to save. When a long-buried secret from Kostas's past unexpectedly emerges, the mission collapses, triggering an existential reckoning. Moving between ritual, memory, and decay, the film becomes a journey into the shadows of both the natural world and the human soul-where truth, guilt, and the possibility of healing finally surface.
