Winchester

In this teaser trailer for the horror film Winchester, a huge, seven-storey mansion with 500 rooms is being built under the orders of a grieving widow, Sarah Winchester (Helen Mirren), the majority shareholder of the Winchester Repeating Arms Company. A man who says he's worried about Mrs. Winchester's sanity convinces a psychiatrist, Dr. Price (Jason Clarke), to talk to her. Mrs. Winchester asks Dr. Price if he believes in ghosts and he tells her he does not. The candles in the room suddenly all go out, and we see a series of frightening events taking place in the house.
