Two lives.

One destiny.

In the small town of Willowbrook it seems like Kairee Sanders and Marshall Washington have a perfectly normal high school life. That is is how it was anyway until the two highschoolers found out there part of a secret race of shape-shifting creatures sent to the human world to destroy all of mankind....and there selves.

After receiving a mysterious call from an unknown caller, Adrian, a detective, is kidnapped and locked inside a mansion with eleven other people. The same caller later tells everyone remotely about their purpose in the mansion; they will each be killed one by one, a death per day unless the detective can catch him/her. For the caller, it is a game. A game of murder.
