Once upon a moonlit sea, a whale was born and began his song of his long and eventful journey through the great oceans. Hruna’s voyage takes him to many things. Seals, dolphins and Ala the seagull all guide him on his travels and help him during times of great danger and great joy. And before his song is over, Hruna is put to the ultimate test when he leads a daring rescue amongst the icebergs, and saves his pod from the whalers.
