I saw this movie like 15-20 years ago, and have been going crazy trying to remember the title ever since. The little information I can recall is this;

there was this woman, dirty blond I believe, who was kidnapped and handcuffed in a basement to a bed, I believe she was pregnant, and there was something to do with him wanting to take her baby or something? She also swallowed the handcuff key and threw it back up to escape.

Any suggestions are appreciated, as I haven’t found a single movie in google searches remotely similar… I know it’s not much info to work with… but like I said it was so long ago, I was very young. 80’s-90’s movie I think.
