After 25 years away in a foreign country the great singer Tino Taviatini (Original name Antoni Domagala) arrives in his native town to give a benefit performance marking his 50th birthday. The maestro arrives in the company of his wife Sophie, his personal secretary Arthur Netz and an entourage of friends representing business circles. Maestro suddenly loses his voice. Taviatini's agent Balmour, who supervises the building of an opera house in Strasbourg, arrives with the news that the local authorities are holding up the project founded by the maestro.
