Plot summary

Julia Banks is being questioned by a detective about the murder of her psychotic ex-boyfriend Michael. Julia claims that she has been set up and that she has nothing to do with the murder, despite social-media conversations clearly showing Julia lusting after him. The scene then cuts to six months earlier, with Julia getting a send-off from her boss and friend Ali, from her job as chief online editor for a storytelling website. Julia is now going to work remotely from the mansion she will be sharing with her new loving fiance, David Connover, and her soon-to-be stepdaughter Lily. Arriving at David's, she is greeted by David's ex-wife, Tessa, who is still not coping with the end of her marriage two years earlier..
