Ten-year-old Omul, his parents, sister Kimi, and brother Mirko live in a small seaside village Krimo. One day, while Omul and Kimi are playing on the beach, a sudden storm rises and a giant wave sweeps the children away. In the sea, Omul sees a mythical creature, Sadumea, steal Kimi’s soul. At the last moment, a whale rescues the children, but when Omul wakes up in the hospital, he learns that Kimi is in a coma. Together with his defiant brother Mirko and a friendly dog named Tela, Omul embarks on a perilous yet beautiful journey towards Sadumea. Drawing inspiration from Studio Ghibli, this wonderful film is uniquely its own.
