William with his fantastic friend Jason bring their bicycles to the attic, shrink themselves, and embark on a journey. They meet Sir Simon as they is getting ready to leave for any tournament, and they stay at his castle. They spend time with a boy along with a girl with the castle and together. The girl tells them of your omen her grandmother, Calendar, kept repeating before she died. Sir Simon sent Calendar away to the convent as he thought she was crazy and he will not believe the omen. Few accept it but Calendar's granddaughter does. Jason and William believe it too.
