The last thing you remember is coming home from work. You'd taken more then a few steps through the door, someone grabbed you from behind. Before you had a chance to even begin to struggle, a cloth was pressed over your mouth. When you breathed in, you were overcome by the strong scent of the drugs soaked into it and everything went dark.

Now, you awaken to find yourself...here. Your first impression is concrete floor below you, concrete walls on three sides and on the fourth: metal bars. As you stir, you hear the rattling of chains and realize there are shackles locked onto your wrists and ankles. A tight pressure around your neck reveals a metal collar encircling your throat. When you try and cry out, in shock, terror and confusion, only a low murmur escapes and you notice the thick rubber plug of a gag filling your mouth.

Peering out through the bars of your cage...no other word describes it so well, your terror increases. In front of you is another wall with more cages and each holds a single, captive girl. Like you, they wear shackles, collar and gag and nothing more. Some look back at you, with expressions of anger, of fright or confusion at your shared predicament.

Your mind races. Where are you? Who are these other captives and why have they, and you, been brought this strange and terrifying prison? Your eyes fall on the placards between the cages. Most seem to simply identify the hapless girl crammed into the cage above or below it, but several have an additional notice pasted over, a single word in bold red characters: SOLD. You don't know what that ominous word means...but you'll find out soon enough...
