Colonia

Although the second trailer for the movie Colonia looks like it's set in the 1800s at first, it actually takes place during the 1973 Chilean military coup. Emma Watson, who plays Lena, knocks on a door in the woods with a sign above it that reads Colonia Dignidad, and is allowed entry. She's told that once she joins them, she has to remain. Lena agrees and is seen working in the fields alongside other women. She's asked by the leader if she has a boyfriend and says no, but that turns out to be a lie and she's beaten in front of a group of people as we see flashbacks to happier times.
