Bordertown

There's a detective series from Finland called Bordertown (Sorjonen). In the first episode a young woman is abducted and taken to a house in the back country.

She's strapped down to a bed in just her underwear and is barefoot. No gag.

The kidnapper is more kind (at least as kind as you can be while holding a woman captive) by feeding her. And, at one point, he even gives her some clothes to wear (while she's still tied to the bed, and even with the clothes, she's BF the entire time).

And throughout her captivity, the damsel is very stoic and brave. Perhaps she's just biding her time to make an escape.

She eventually rescued by the Sherlock Holmes-type detective that this series is based around.

The clip by Jakob88 also has a brief scene with a barefoot woman fending off another woman who is locked in a bathroom. All in all, this is a very nice clip, and you can see it right here.
