<P> Later that night at the festival, during their final number, the von Trapp family slip away and seek shelter at the nearby abbey, where Mother Abbess hides them in the cemetery crypt . Brownshirts soon arrive and search the abbey, and the family is discovered by Rolf . Upon seeing Liesl, he hesitates raising the alarm long enough to allow the family time to flee, and the family is able to escape using the caretaker's car .
