This true story happened in the place of Germany where Robert is a doctor in a hospital. He has been suffering in his personal life ever since his girlfriend Mercy died. On a dark thundery night, Robert is on his way back home when he meets a white frock clothed girl in distress. He offers help to her, giving her a lift in his car. She accepts his help and introduces herself as Jessy. As soon as she steps in the car, the wipers eerily stop working. He's even more surprised when the lady shows him the way when it isn't visible and guides him outside a graveyard. En route he notices her finger is bleeding, when asked, she tells him “I like blood”.
           

Jessy disappears inexplicably and after a few minutes, a troubled father stops his car begging him to save his daughter's life. He follows the man and comes to an old run-down mansion, but unfortunately the girl in question is already dead. He is surprised to see that the girl is Jessy. When he goes back, he encounters some policemen who tell him that the place has been empty for a while and that rumours are that the place is haunted. The policemen inform him that what he saw in the mansion was exactly what happened years ago and that the haunting started after her death.
Shaken and attracted by this incident, Robert decides to investigate further. He finds that Jessy is as interested in him as he is in her: Jessy can appear to him at will. Later his mother arranges his marriage and to his shock his bride-to-be is none other than Jessy. He begins to see Jessy everywhere, while others claim that she was with them the whole time.
Jessy gives him differing treatment every time they meet, and Robert decides to solve this mystery. Though his well-wishers believe that something is wrong with him, luck smiles on him one day. Robert manages to follow Jessy undetected into a secret home. There, he is shocked to see Jessy, the "troubled father" and the "policemen" he encountered earlier in the story. He realizes that the plan is larger than he thought. He sneaks into another room, only to get another surprise: Jessy is kept prisoner there. He is also surprised to see Jack there with the fraudsters. He realizes that Jack is trying to take his property by proving him to be mentally unstable. He confronts all of them, which results in a fight.
Robert is also shocked to learn that Jack killed Mercy for his greed. Jack knows that a treasure is hidden somewhere in the mansion. In the scuffle that follows, Jack accidentally guns down fake Jessy. The real Jessy explains that she had a twin sister who went missing as a child. She grew up to be an evil woman whom Jack used for his purposes. Based on the facts, Jack is arrested. Finally, Robert and Jessy are able to start their marital relationship on a good note.
