Your plan went perfectly. The alarm never rang, the vault opened quickly and the diamonds are exquisite. As you are handing them to your partner, you get a strange feeling. Everything was… too easy.
As soon as you let go of the bag, your eyes start to close, your legs give away and you fall unconscious. Something is definitely off! When you wake back up, you are handcuffed to a chair and strident bell is ringing. It was all a set up! Your partner left with the diamonds, slipped you a sleeping pill and pulled the alarm! Will you be able to destroy all evidence of you being here before the police arrives?
