Charlotte and her classmates are locked in a mansion. At first, thought it was a prank. Until someone dies. Now they have to find the truth. One dead, 23 alive and one absent girl. Spoiler alert: they all die. (or do they?)
It started out as a bet, a harmless bet. But what lies inside the mysterious place? A ghost? Treasure? Traps? Or maybe it's just a normal mansion? And how would it affect the rest of their lives?
