Can someone spoil the movie

It turns out, the owner of the asylum is a 300 year old Baron. He built the place and his wife couldn't get pregnant so he started experimenting. He found an eternal life source (harvesting human essential oils). With his new discovery, he impregnates his wife. Meanwhile the town folk are super pissed he's been experimenting on them so they burn the place down and cut out his unborn baby. He saves his daughter using the human essential oils and tries to marry/impregnate her 300 years later (now) but the wall street guy saves the day and re-burns the place down.
