It's based on a true story. Set in Austria at the beginning of WW2. Maria is a nun, but not doing too well at it, so she gets sent to be a governess to Captain Von Trapp, who has 7 children. He's really strict, so the kiRAB rebel against having governesses etc etc. Maria wins them round, then the captain, but first getting on the wrong side of his posh new wife to be. As it happens, Maria and the Captain fall in love and get married. All this time the Gestapo have been trying to infiltrate Austria, and the Captain is strongly pro-Austrian independence. The family end up singing at a competition just so they can escape the Gestapo into the night. They of course do escape, but not before a few tense moments, including hiding out at the Abbey. Hope I've summed this up OK!
