Isabella is stretched on a rack in a medieval dungeon, because she was curious to experience how it felt to be tortured by inquisition on witchcraft charges.
Isabella wanted to know how it felt to be captured as a witch in medieval times. She was taken to a dungeon, shackled, undressed and stretched on a rack.
Isabella experiences how it was in the days of Catholic inquisition. She is taken to a medieval dungeon and shackled to the wall, waiting for "skin crawling" torture to begin.
Isabella got arrested and imprisoned. She was told to undress and got cuffed, then positioned for taking a mugshot. She thought that the arresting officers went a little over the line of standard procedure, but as a young, inexperienced and naive girl, she obeyed whatever they commanded.
Isabella wanted to experience medieval inquisition and was shackled in a real medieval dungeon as a witch. Most probably real medieval inquisitors would only wish that all witches would look like her. She is now waiting to be stretched on a rack.
