Rosa is a stern disciplinarian obsessed with raising her daughter Lucy as a straight-A student and shielding her from any form of distraction no matter how minor. Lucy tries to tolerate her mother, but when the latter goes through extreme measures just to ensure her goal, Lucy finds it difficult to shake off the idea that her own mother could be the bane of her existence.
