At some point during the third Ginger movie Girls Are For Loving, the grown daughter of a US senator has been kidnapped.
She's relaxing with her boyfriend/husband on a sailboat, barefoot and clad in a bikini.
But fun times are interuppted by scuba diving bad guys who board the boat.
She's stashed at the bad guys' lair, still clad in her bikini and bound with her wrists above her head.
Ginger's partner, played by Timothy Brown, goes to rescue her, and winds up in a battle with one of the evil minions. The woman can be seen in the background of this fight.
Despite the briefness of her bondage, I still like this little scene. I don't know the name of the actress. Her character doesn't even have a name in the film, other than being known as 'senator's daughter.'
