After Vivien Harmon has a miscarriage and catches her husband, Ben, cheating on her with one of his young students (he's a psychiatrist), the couple moves from Boston to LA with their daughter, Violet, for a fresh start. Once they purchase a gorgeous Victorian mansion, they learn from their real estate agent that the couple who lived there before them died in an apparent murder/suicide. It eventually becomes known that more than 20 violent deaths occurred in the home, which is why people call it "The Murder House." As the family settles in, bizarre things start happening, and they are unaware that they are being haunted by ghosts, including their maid, next-door neighbor, and one of Ben's patients, troubled young teen Tate Langdon.
