For this one, I would be a tourist travelling through Europe. I would come across a woman desperate for money to leave the country, with her telling me that she had been held by a wealthy, powerful businessman or crime boss, as their exotic maid and slavegirl. Giving her money to escape the country, I find myself snatched from the street, or my hotel, brought to him, and surgically altered to take her place, with a new face, a bigger bust, even new fingerprints, with no way to escape my new life.
If this appeals to anyone, let me know.
