In the charming New England town of Nantucket, Dr. Kate Lawrence, a celebrity relationship expert, shoots another dating advice video for her popular blog. Later, at a farmers market, Kate shops with her fiancé, Bryan, a handsome and perfectly polished businessman. There, Kate runs into Lucas Wright, a carpenter specializing in handcrafted furniture, who has had a crush on her since their high school days. Hoping to land a book deal, and urged by her aggressive show-business agent, Kate plans to publicly announce her engagement - and film the subsequent wedding arrangements for her blog - as a way to build her fanbase.
At an upscale event, as Kate prepares to share the news, Bryan shocks her by breaking up with her and calling off the wedding. Wanting to save her from humiliation and protect her public image, Lucas steps in and pretends to be Kate's fiancé. With her career at risk, Kate reluctantly moves forward with her agent's plan to let the public continue believing that Lucas - whom she considers just a friend - is her soon-to-be husband. As a film crew shoots Kate and Lucas' wedding preparations, the counterfeit couple starts to develop real feelings for each other. When Lucas declares his affections, Kate panics and - fearing a relationship would end in heartbreak - pushes him away.
As her career soars, Kate feels guilty about betraying her fans and decides to confess that Lucas is not her fiancé. But before Kate can apologize, Bryan's new girlfriend posts a viral video, exposing Kate as a liar and her engagement to Lucas as a fraud. With her career and life now in shambles, the young relationship expert learns an unexpected lesson about love, and sets out to revive the romance she let slip away.
