I would be new to a city, a tourist, or on a working visa, in Europe, the US, Canada even. I would help someone to escape the city, giving them money to get far away from their captor. They could have been forced to work as their maid, streetwalker, bondage slavegirl. They successfully escape, but my part in it is found out, and Im kidnapped, made to take their place and live their life.
There could be some alterations, breast implants, facial alteration, no brainwashing or hypnosis.
If this interests anyone, let me know.
