Sophie and a companion are exploring a mysterious room in their house, which they have discovered is connected to a magical walk-in closet. They are trying to uncover the truth about the room and the house, but are scared and unsure of what they will find. They enter a corridor with multiple doors, but find that most of them are blocked or locked. They try to open the doors, but are unsuccessful. They discover a large intercom and try to use it to communicate with someone, but it doesn't seem to work. They then find a key that they had previously hidden, which they hope will help them unlock the doors. They are excited to continue their adventure and discover what's behind the doors.
