Questions about Hidden 2?

Because he is a psychopath, combing the story can be seen:

At the beginning of the twentieth century, the woman in white and her son Parker lived alone in a big house. I don't know why, the woman in white hates her husband and is psychopathic, dressing her son up as a girl.

When he grew up, Parker was born abnormal. Parker killed his mother at her request. Dressed as a widow in black, he killed many young girls one after another and hid their bodies at home.

Old Parker tried to castrate himself and was injured and admitted to the hospital where the hero mother worked. In the hospital, he met Josh, a young man. Parker is dead.

Josh had the ability to get out of his body in his sleep when he was young, so Parker's soul kept staring at him and following him, waiting for an opportunity to take his body. Parker's soul appears in Josh's photo as an old widow in black.

The man and mother who found the photo abnormal called Alice the psychic. Alice and her partner noticed the existence of Parker's soul. They sealed Josh's ability to leave his body and made him safe for the time being.

Josh's son also inherited his super powers, lost in the spiritual world during his OBE, and his body was attracted by a red-faced demon. In order to bring back his son, Josh went to the spiritual world to look for him. The persevering Parker ghost finally waited for the opportunity to rob the man's body and killed the psychic Alice.

In the second part, the woman who saw the photos left by Alice at first became suspicious of her husband. The couple lived in the man's mother's house with their children. Josh's homeless soul plays the piano to attract his wife's attention, and the soul of the woman in white also comes to reunite with her son. Suddenly, with a beautiful wife and several children, Parker was a little shaken. He didn't want to live the abnormal life before, but also wanted to feel the happiness of his family. Unfortunately, his soul was so old that his body began to collapse. The woman in white took the opportunity to encourage him to kill everyone, claiming that only in this way can we keep our body now.

The man's mother suddenly burst into various potentials and followed Alice's new and old partners to dig up all kinds of insider information, which led to the Armageddon. The dead Alice helped them in the spiritual world. We fought bravely, eliminated the ghost of the woman in white in the chaos, indirectly expelled Parker's ghost, Josh got his body back, and everyone else returned to his soul. Everyone is very happy. Although Alice was a ghost, she continued her work before she died.
