THE ONLY WAY TO SURVIVE...IS IF SOMEONE CONFESSES TO MURDER.

Seven people wake up in a remote mansion. The doors are all locked.
They have no idea where they are. Who brought them there. Or how to escape.
Each knew the victims of a dreadful crime committed four years earlier but that's all that links them.

Then a voice echoes through the house with a terrifying message.
They've been poisoned - and have less than 12 hours to live.
There's an antidote on hand: but only if someone admits to being a killer.
And they all claim to be innocent.

The time for confession is rapidly running out.
How many - if any - of them will survive the night?
