Kelly Fitzpatrick has never experienced the so-called "luck of the Irish (think Melissa McCarthy/ Kate McKinnon)." Instead, while working sanitation at NYC's St. Paddy’s Day parade, she embarrassingly runs into the love of her life, who's engaged to her arch nemesis. However, thanks to her chance exchange with an exceedingly mean man—who claims to be a magical leprechaun—Kelly's shocked to find he granted her Irish Super powers. She decides to use these powers to reel in the man of her dreams.
