The Young Indiana Jones Chronicles S02E01 - Austria, March 1917

Old Indy has posted a wrong parcel by mistake and is trying to get it out of the mailbox when a postal worker scolds him. He starts to tell her about the last time he had so much trouble delivering a package, during the Great War. Under the alias of Henri Defence, Indiana Jones was a spy in the Belgian Army. He had to safely escort two Austrian Princes to their family in order for their country to begin a separate peace treatment and deprive Germany of it's strongest ally.
