Omul lives with his family on a remote island in the Fire Archipelago. During a beach trip, a storm sweeps Omul and his younger sister Kimi into the sea, where Omul witnesses a mysterious creature threatening Kimi’s soul. Rescued by a whale, the siblings survive, but Kimi is left in a coma. Omul’s ability to talk to animals becomes crucial as he and his brother – who blames him for the accident – set out to find Sadumea, the mythical figure behind Kimi’s torment. With their dog Tela, they embark on a dangerous expedition deep into the island to save Kimi…
