Wild Dog: Sinister and savage psychological thriller

A house on a French hillside. Two couples: the wife of a doctor presumed killed on the battlefields of the First World War, and a mysterious German lion tamer hiding his circus animals from requisition; and Parisian Franck and his wife Lise, who has booked them into the isolated gite to escape twenty-first century life. When a hungry wolfdog emerges from the forest, Franck begins to discover dark secrets about the house, and himself.
