The three magicians stand in amazement in front of the huge gates of the old castle, which have just opened as if by magic. Do we dare go inside to see if it's really haunted? Conrad asks a little anxiously. Yes, together as a team we can do it! Vicky and Mila answer in unison. But the gates are creaking again Can the three of them explore the old walls and find their way out in time before the haunted castle closes its gates again until the next full moon? Because one thing is certain: if ghosts really are up to mischief here, they will certainly do everything they can to stop our three curious magicians!
