To celebrate the 50th Anniversary of the classic film "The Sound of Music," Diane Sawyer tours Salzburg, Austria, and the surrounding Alps, with its star Julie Andrews, revisiting many of the actual locations and reflecting back on the most successful movie musical of all time.

ABC News Anchor Diane Sawyer takes viewers on an incredible journey to Austria with Oscar-winning actress Julie Andrews, exploring the mystery of "The Sound of Music" story that captured the world's attention and endured for so long. With unprecedented access, Sawyer goes behind-the-scenes to show viewers what happened beyond the frame in those famous movie scenes and re-trace the steps of the real von Trapps, who defied the Nazis and were forced to leave the country they loved.

In the special, Sawyer and Andrews re-create the magic. Andrews opens up about her real life and her fictional one as Maria. ABC travels to landmarks including the meadow, fountain, gazebo, Mirabell Gardens and St. Michael's Church, among others. Andrews talks about her favorite and least favorite songs, and Sawyer combs through photographs and video from the set and of the real von Trapps, and meets some of the many tourists who trek annually to the town of Salzburg.

For the first time, Andrews ventures to a part of Austria she's never been - the house where the real Maria von Trapp lived - and goes with Sawyer to the train station the family used to make their escape. Mother Abbess of the Nonnberg Abbey emerges from those sacred walls to tell Sawyer what she really thinks about the film. And Christopher Plummer, who played Captain von Trapp, shares his insight on the movie and his special bond with Andrews.
