Check out the particularly gory, The Windmill Massacre trailer.
The film stars Charlotte Beaumont, Ben Batt, Adam Thomas Wright, Fiona Hampton. Nick Jongerius directs.
Jennifer is an Australian girl on the run from her past who washes up in Amsterdam. In a desperate attempt to stay one step ahead of the authorities, she joins a coach-load of tourists embarking on a tour of Holland's world famous windmills. When the bus breaks down in the middle of nowhere, she and the other tourists are forced to seek shelter in a disused shed beside a sinister windmill where, legend has it, a Devil-worshiping miller once ground the bones of locals instead of grain. As members of the group start to disappear, Jennifer learns that they all have something in common - a shared secret that seems to mark them all for doom.
