Her parents have gotten divorced, she’s moved into an apartment that smells like bologna, and she is being forced to face her sister’s killer and a courtroom full of people who doubt what she saw in the corn maze a year prior. Claire was an all-American girl, beautiful and bubbly, and a theater star. Alice was a nerd who dreamed of becoming a forensic pathologist and would rather stay at home to watch her favorite horror movies than party.

On the first day of the murder trial, as Alice prepares to give her testimony, she is knocked out by a Sidney Prescott look-alike in the courthouse bathroom. When she wakes up, it is Halloween night a year earlier, the same day Claire was murdered. Alice has until midnight to save her sister and find the real killer before he claims another victim.
