Bobby Henrey, the amazing juvenile star of The Fallen Idol, is here cast as 7-year-old musical genius Sebastian Giro. Mistreated by his avaricious adult manager, Sebastian runs away to a remote Alpine village. He then falls into the hands of a gang of kidnappers, led by the basically sympathetic Jack.

Phillipe, the son of an ambassador in London, idolizes Baines, his father's butler, a kind of hero in the eyes of the child, whose perception changes when he accidentally discovers the secret that Baines keeps and witnesses the consequences that adults' lies can cause.
