Behind the Locked Door

Aricin and Mirren Guvald's family move into a strange and nearly abandoned manor in the middle of nowhere without their parent's even visiting the house before purchase.
The spooky old house has a lot to offer in terms of adventure for the two children, however, a single door in the hallway off of the kitchen captures their attention more than anything else. It is locked with three different and secure locking mechanisms but the children soon find out something or someone is trapped behind it.
Little do they know a secret is what is trapped behind the locked door. A secret involving their own family.
