Ten strangers.

An old dark house.

A killer picking them off one by one.

And a missing girl who's running out of time. . .

Ten strangers wake up inside an old, locked house. They have no recollection of how they got there.

In order to escape, they have to solve the disappearance of a young woman.

But a killer also stalks the halls of the house, and soon the body count starts to rise.

Who are these strangers? Why were they chosen? Why would someone want to kill them?

And who - or what - is the Beast in the Cellar?

Forget what you think you know.

Because while you can trust yourself, can you really trust THE OTHER PEOPLE?
