For this one, there are a few variations.
I could resemble the escaped wife or girlfriend of a mob boss, or a powerfull LA gang leaders kept girlfriend, or even the prized prostitute of a well connected pimp. I would be snatched from the street as I resemble them, with the truth coming out later. Of course, by then its too late, so instead of being released, I'm trained in everything that they were, unable to escape, altered to look a bit more like them if need be.
If any of these appeal to you, let me know and we can work out the details.
