Scottie Price, the only woman on her new team, invents a nonexistent husband to impress her boss. When her lie is exposed by a keen co-worker, she fabricates an unhappy marriage, leading her boss to arrange a session with the best marriage counselor in the Northeast—who happens to be her boss's husband. Desperate, Scottie enlists her best friend's improv-obsessed millionaire brother, Wilder Wells, to pose as her husband. Their fake marriage takes an unexpected turn when Wilder's improv rule of 'always say yes' lands them in an eight-day summer marriage camp with all of Scottie's co-workers, forcing her to share a cabin with her way-too-handsome fake spouse.
