Literature professor Harriet "Harry" Wild (Jane Seymour, Dr. Quinn, Medicine Woman) is struggling to adjust to her recent retirement when she's mugged. While recuperating at the home of her son, Charlie (Kevin Ryan, The South Westerlies), a senior detective in the Dublin police, Harry reads his case files and notices that his current murder inquiry bears striking similarities to an obscure Elizabethan play. After Charlie rebuffs her input, Harry decides to find the killer herself to prove she was right. Little does she realise that this decision will lead her to a whole new life. When Harry crosses paths with wayward teen Fergus Reid (Rohan Nedd, Whitstable Pearl), she recruits his help in her investigation. Much to the dismay of Charlie and his wife (Amy Huberman, Finding Joy), soon the unlikely pair are solving mysteries ranging from fledgling serial killers with Dostoevsky fixations to kidnappers, con artists, and psychopaths.
