I can't remember the movie but it was on Netflix. This girl left home because she hated her mom and wanted to find her dad and after a one night stand, the guy held her hostage at his house with his mom. He had her in the basement with his nursery. of plants. When the dad came home ,it turned out he was her father and he wanted to teach her how to kill.
