Chuck Brewster, the former business partner of Ali Reynold's tech entrepreneur husband B. Simpson, once carried on an illicit affair with Clarice-- B.'s first wife-- while his own wife lay dying of breast cancer. Once the affair came to light and tore both families apart, Chuck and B.'s partnership dissolved. Now, decades later, Chuck is found stabbed to death in his bed with Clarice standing at the top of the staircase, wearing a bloodied nightgown and holding a blood-covered knife. Jailed on suspicion of homicide, Clarice calls B. to ask for help and ends up reaching Ali instead. Although B. washes his hands of the whole situation, Ali suspects there might be more to the case than law enforcement thinks. Against her husband's wishes, she sets out, determined to find the real killer. At the same time, someone is targeting Camille Lee, High Noon Enterprises's outside salesperson. While she's on the road closing high-profile deals, it appears there's nowhere she is truly safe. With the help of Frigg, Ali's trusted AI, Ali fights to protect her employee and clear Clarice's name. As accusations abound and hidden histories come to light, Ali races against time to determine where everyone's true allegiances lie and to find the killers before innocent individuals are either convicted of murder or end up dead.
