Movie about kidnapped woman

I remember watching a movie on tv in the late 80s/90s about a woman who was kidnapped. It took place in the 30s or 40s but was made in the 80s/90s. It was in English, in color and not a tv episode. I want to say I saw it on a channel like Lifetime but it was not on any lists of Lifetime movies. I think the title was something dramatic like “The Kidnapping of Jane Doe” but I am not certain. She was kept in a wooden shed or something. I remember her wearing a leather bomber aviator-like jacket at one point in the movie. I think two men had kidnapped her. I think she tried to escape but got caught. I just remember the woman was brunette, and at the end they took her to a general store/five and dime store and she walked down an aisle, grabbed a box of rat poison, opened it up and ingested it. The kidnappers were freaked out. Then she died? a few hours later.

Got something to say?
