My first idea is a waterworld one, kind of like the movie. I could play a female trader with gills just like the mariner. Its open to ideas as to what would happen in it.
Another is where im holidaying in Atlantic city, or Las Vegas. Im seen by a mob boss in a casino, who sees that im the splitting image of his missing mistress or new wife. He has me snatched and brought up to his penthouse apartment. He listens to my story but decides that my passport and any other id is fake, and that im covering up my accent with a fake australian accent, and does what he can to 'return' my old accent, and has me stay with him until he's sure i wont try to 'escape' again.
Another similar one is where im travelling through russia or the ukraine. Perhaps i was near a war zone and my rented vehicle was destroyed. i could have been taken by a warlord or high ranking officer as his own personal plaything, kept in a perfect catholic schoolgirl uniform, or military one perhaps.
Just some ideas that i thought i would put out there, see who likes them.
