Double

Just when Wang Wei, a private owner, is worrying about the operation of his health preserving club, his father Wang Dezhi, who joined the scientific expedition team by chance 20 years ago and has been missing for so many years, suddenly appears in front of him. 20 years has passed, but his father doesn't look old. However, his memory is in disorder as if he came from another space. He tells Wang Wei about what happened in the scientific expedition team: A group of people drove into the desert to conduct scientific investigation. Just when they returned, they discovered a submarine which should have appeared at the other side of the earth. Anyone who touches the meteorite will open a parallel space, bringing himself from another space. In order to survive, they had to fight.
