The last time that I saw this movie was in the mid-eighties in the east-german television. At this time I was a boy,and now I am looking to see this great movie again,but it is not showing in TV,or on a videocassette or dvd again. The story is about a boy,who is called by a friend to come to an old castle. The problem at this castle is that several doors are being stolen.The question is now why they are stolen and who is the thief of the doors? The boy will investigate this problem and he solve the case. I looking forward to see this movie sometimes again,perhaps i will find a copy of it in poland from where this movie are coming from. joerg
