Cynical Sally, Lara Jean Chorostecki, lives a life with little excitement or romance. Although she hopes to become a novelist, she makes ends meet by ghost-writing a local advice column under the alias Mr. Know It All. When a celebrity endorsement pushes the column into overnight fame, the newspaper asks for a photo of the author. Sally’s best friend and agent, Kristina Pesic, has been spinning a lie, claiming that a man has been writing the column all along. To appease the paper, Sally submits a sketch of Albert, Jefferson Brown, a handsome stranger she spots in a movie theater, who, to everyone’s shock, turns out to be a contract killer.
Once the picture goes public, the man who was pictured cannot walk down the street without drawing attention. To protect his cover, Albert decides to kill Mr. Know It All, the very persona behind Sally’s now-famed column. While determined to track down the elusive writer, Albert agrees to participate in a hidden-camera interview with the columnist to satisfy the press’s insatiable need to know more about the mysterious author.
As Sally and Albert spend more time together, the original motives behind their interaction begin to blur, giving way to a fragile, growing attraction. Sally finally confesses that she is the author behind Mr. Know It All, a revelation that leaves Albert torn between one path that could lead to love and another that could cost him his life. His seeming indifference only deepens the tension, and Sally finds herself pulled between trust and fear, unsure of whether she can truly believe the man she’s begun to fall for.
Meanwhile, the Mob Boss’s heartbreak after reading an issue of the column sets off another chain of consequences. The Mob Boss, Al Sapienza, is left aching and makes the drastic decision to hire a hit-man to kill Mr. Know It All, ultimately choosing Albert as the blade between love and loyalty. Albert stands at a perilous crossroads: follow orders and risk losing Sally, or defy the mob and chase a chance at happiness. The stakes rise as the one-legged man, Dylan Roberts, enters the fray, hinting at his own quest for revenge and adding a further layer of danger to an already perilous situation. Will Albert carry out the hit, or find a way to outsmart the mob and protect the fragile bond forming between him and Sally? And can the truth survive the escalating threats around them?
