Talented footballer Vitalii Petrenko, his mother Tetiana, and little sister Nadia flee the war in Ukraine and settle in the outskirts of Bath. Their arrival coincides with fish mysteriously disappearing from supermarkets and ponds all over Bath. Vitalii is befriended by hopelessly disorganised but history-loving Edward Austen who shows Vitalii Roman coins that he has discovered in his back garden. While waiting to consult the Roman Bath’s Curator, Vitalii accidentally drops magic coins into the warm water which awakens a Ukrainian three headed dragon Zmiy Horynych.
