Burning Secret is a 1988 drama film, based on the 1913 short story Brennendes Geheimnis by Stefan Zweig, about an American diplomat's son who befriends a mysterious baron while staying at an Austrian spa during the 1920s.

While being treated for asthma at a country spa, an American diplomat's lonely 12-year-old son is befriended and infatuated by a suave, mysterious baron.

During a story of his war experiences, the baron reveals the scar of a wound from an American soldier and thrusts a pin through it, saying "see—no feeling."

The film was written and directed by Andrew Birkin, and stars Klaus Maria Brandauer, Faye Dunaway, and David Eberts.

According to Birkin, the making of the movie "was something of a nightmare" with the two lead actors thoroughly disliking one another and other problems while shooting on location in Mariánské Lázně while directing young David Eberts was "a joy".
