You are invited...

To the annual game where teenage competitors search Sky Manor for the key to open a vault hidden behind the deceptive walls. The winner will have the wealth of a lifetime, but there is one catch.

One contestant must die.

This year, seven people step off the zeppelin to compete. A banker's son. A rich gentleman. A nice girl. A poor shopkeeper. A gold digger. An outsider. A thief. All have secrets of their own, and all have reasons to kill.

When one player turns up dead, the other six find themselves in a game of cat and mouse, the murderer among them.

Who will win, and who will die?
