High school student Wendy (Mary Elizabeth Winstead) went to the amusement park with her friends to celebrate graduation. Everyone had a great time. The lights in the amusement park were bright, but there were strange things everywhere. When she sat on the roller coaster seat, Wendy suddenly saw a strange phenomenon and was terrified. Her boyfriend Jason comforted her that it was just an illusion. The roller coaster started, but suddenly derailed in mid-air, and everyone was hanging upside down in the air. Wendy watched her friends fall to death one by one, and she was not immune. Wendy was awakened by her classmates' shouting and realized that it was just an illusion, but she was worried and tried to stop everyone from leaving the roller coaster. Although she was laughed at by everyone, it turned out to be the right choice. The roller coaster had an accident just as Wendy saw it. However, the boys and girls who escaped the disaster did not escape the clutches of the god of death. They died one after another. Wendy found that all this was related to a photo in the amusement park. In order to survive, she began to fight with the god of death.
