While Emma is recovering from a traumatic brain injury, she dreams of her husband's body floating in the lake, surrounded by blood. She ignores the sense of foreboding and joins Paul on a boat to celebrate his securing a big new client. By the end of the night, Paul is dead and Emma wonders: Did she see the future, or did create it?
Detective Garrett, the investigating officer, has the same question.
After another death occurs, Emma struggles with what is real and what is imagined. Is there a murderer out there who is watching and waiting for Emma? Or is Emma the villain?
