You try to escape

Bleak chances or not, you are not going to be a slave. You will not be fucked, bound, tortured and sold at the whim of whoever happens to own you. Thus you grab the sharp-edged lock with your hand, and start to cut through the material. The rubber itself is sturdy, so you work slower than expected. However after an hour you successfully get through the cuff on your left hand, and in the next two hours you manage to get through both cuffs on your ankles.

You take out your ballgag, and go to the container where the whip was put earlier. To your surprise, you find an electric baton next to it, so you grab it, go to the door, and press your back against the wall.
