I could be in an unfamiliar city on business, or holiday, be seen by someone looking for a new prostitute or escort, and kidnapped by them. I could be framed or set up for something that I didnt do, or even altered to look like someone else, someone who would be in demand. I would be unable to escape my new life, and have to adapt.
Another idea is bodyswapping. I could be in town, meet up with an escort or prostitute, and when I wake up, I'm in their body and they've escaped in mine, if anyone is into that sort of thing.
If either of these ideas interests anyone, let me know.
