Castle Rescue

From the Lego Indiana Jones Wiki

Indiana and Elsa venture to the castle, where Indiana fools the entranceway's butler by swapping clothes with Elsa. After a brief fight, Indiana and Elsa crash into Henry's holding cell, where an enemy named Colonel Vogel steals the diary from Indiana. Elsa reveals that she's in league with the Colonel, and the two tie up Indiana and Henry. Indiana frees himself and his dad with a candelabra, and the father-son team fight their way through the castle. After battling an enemy radio operator and fooling some guards by wearing disguises, Indiana and Henry escape.
