Witnesses (2014)

Set in a small coastal village in France, this is a quiet thriller of crime and dark secrets. The opening sequence takes place in a house just put out for sale. In it, the discovery of what appears to be the dead family in the house, implicates the former chief-of-police to the plot. The now-retired chief-of-police, having made a lot of enemies in his past career, is recovering from a car crash which he barely survived.
