Someone’s framing Hailey Dean’s (Kellie Martin) friend in the third and final new “Hailey Dean Mysteries” movie of May 2019, and she’s not going to let that slide.

“Hailey Dean Mysteries: Killer Sentence,” the latest installment in the Hallmark Movies & Mysteries franchise based on Nancy Grace’s book series of the same name, premieres tonight, and the case is extra personal for the main character.

According to the synopsis, “When a freshly paroled killer that former prosecutor-turned-psychotherapist Hailey Dean (Martin) helped put behind bars is murdered and Hailey’s friend, DA Paulina D’Orazio [Lauren Holly], is charged with the crime, Hailey and Fincher Garland [Viv Leacock] must find the real murderer in order to exonerate Paulina, who is set to face a career-destroying trial that could see her spend the rest of her life in prison.”
