The Maestro tells the story of Arun, a composer and conductor who tried to make it in Europe but has ended up teaching high society children in Thailand. For years, he has been composing a magnum opus, The Tongues of Angels, and dreams of premiering it under his own baton. The Covid crisis allows him to create an imagined utopia for gifted young musicians in the middle of nowhere, far from the pestilence and corruption of the outside world ... but things go horribly wrong.
