The Cottage

Forced into hiding after their kidnapping plan goes awry, two rival siblings, David (Andy Serkis) and Peter (Reece Shearsmith), find themselves fighting for their sanity while they hole up in a secluded country cottage. Weighed down by a hostage who refuses to stay quiet, or tied down, they are soon held captive by their own victim.
But everyone's problems go from bad to worse when they come face-to-face with their psychotic axe-wielding neighbor - a demented farmer with a dark, nasty secret buried where you'd least expect. (official distributor synopsis)
