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.

Next you take the ballgag out your mouth, and go to the closest container to get something that you could use as a weapon. To your surprise, you find an electric baton, so you grab it, go to the door, and press your back against the wall.
