A man got confused by a supernatural appearance of a woman.

A doctor, whose colleague a woman (who fell in love with him) and another male doctor got murdered under mysterious circumstances, is happy to get back to his ancestral house. But since an image of a woman keeps recurring in his mind, he's branded as mentally unfit and those around him decide to admit him in a hospital. What happened to the doctor in the end? Who's that woman he keeps getting images of?
