The von Trapp family are struggling to survive in America, where their performances of European church music are not popular with the audiences. Only when they start performing more upbeat Austrian folk songs and even some American numbers do they become a success and finally find security and a new home.

"The Trapp Family" is a true story based on the popular novel by the Baroness Von Trapp of Austria. The film was made in 1956, some years before the other film based on the Trapp Family's life was released - a little movie named "The Sound of Music".
