Beth Ralston, a paralegal in Portland, Oregon, would rather be racking up billable hours than mingling at an office party --- especially when her sister Lindsay, aka her plus one, is a no-show. After making her obligatory rounds, Beth returns to her office to find that her boss has been murdered. She sees a woman fleeing the scene. Was that Lindsay? Unable to catch up to her in time, Beth waits for the police to arrive and notices that Lindsay has left her phone behind with an unsent text message to Beth displayed on the screen: “Don’t ask. Don’t follow.” While retracing Lindsay’s steps, determined to bring her home, Beth uncovers what her sister, an investigative reporter bent on changing the world, was trying to expose --- corruption, secrets and betrayal on an unimaginable level.
