Kate Battista systematically prepares meat mash once a week, dutifully serving it every night to her father and younger sister Bunny. Her father, Dr. Battista has calculated ingredients for efficiency, but his most recent and desperately devised plan involves Kate in a whole new way. One day Kate’s father calls her at home under false pretenses, feigning that he’s forgotten his lunch. His motive is simple: he wants his daughter to marry Pyotr Cherbakov. Pyotr works as a research lab assistant with Dr. Battisa and his work Visa is about to expire.
Kate is offended and hurt by her father’s lack of sensitivity. Taking a stand, she refuses to do her father’s income taxes. Not only does Kate manage the household affairs, she is also expected to enforce her father’s rules, rules which include that her spirited sister Bunny is not to have boys in the house during Kate and her father’s absence. After work one day, Kate comes home to discover Bunny and Edward, an older next door neighbor, alone together. He is supposedly teaching her ‘Spanish.’ Edward’s influence becomes much more suspicious as the story unfolds.
One evening Professor Battista uncharacteristically, and with the help of a few drinks, pours out his heart to Kate which results in her giving into her father’s charade. She agrees to conspire with her father and marry Pyotr Cherbakov for immigration purposes. Gradually life begins to take a turn and a flicker of hope sparks in Kate as she muses over the potential to move from home and her dead-end life.
Pyotr and Kate begin doing things engaged couples usually do: grocery shop, sharing dinner together and so on. All the while Dr. Battista films these activities as evidence of their sincerity. At the market Pyotr grabs pork to which Kate objects. Edward’s influence has converted Bunny to veganism complicating Kate’s meat mash dish. Pyotr comments “In my country they have proverb: ‘Beware against the sweet person, for sugar has no nutrition.’” Beguiled but on the defensive, Kate quips back “Well in my country they say that you can catch more flies with honey than with vinegar.” Pyotr declares her his ‘Vinegar Girl.’ He is able to see beneath her acerbic character and a growing but awkward relationship begins to bud.
On the day of Pyotr and Kate’s wedding, Pyotr does not show up leading to a suspenseful and comical yet sweet ending.
