Officer Violet Babineaux is called to the scene of a suicide where she finds her childhood friend Charlotte Labarre lying on a blood-soaked couch with a gun in her hand. Violet believes she could have prevented her suicide with a simple call. While placed on administrative leave, guilt drives her to investigate on her own, starting with Psychology Professor Daniel Russo who had an inappropriate relationship with Charlotte, his student. Violet portrays a vulnerable facade to entice his interest, however she falls for his charms. And Dr. Russo’s news of Charlotte’s secret diary threatens to blow the case wide open.
Unsure about Dr. Russo’s involvement, Violet presents a bold conspiracy theory involving cops to her partner Lenny Blake, but he and Homicide Detective Walter Wild dismiss her despite the evidence. When Violet finally acquires an elusive piece to the puzzle, the answers are far worse than not knowing.
