Gretchen Benton is the maid of honor at her best friend’s wedding when she gets drunk, says exactly the wrong thing and feels alone in the midst of all the couples. She can’t avoid weddings—she’s a florist. She also can't avoid the thugs who break into her shop and assault her the following night. To combat her fear after her attack, Gretchen enrolls in karate classes at a local dojo. Soon she's caught between her handsome martial arts instructor and the cute cop assigned to her case. As she begins mastering the basics of karate (while sweating enough to make her mascara run), Gretchen learns that kicking like a girl doesn’t imply weakness, it means striking hard and striking with style.
