Meet the Park Family: the picture of aspirational wealth. And the Kim Family, rich in street smarts but not much else. Be it chance or fate, these two houses are brought together and the Kims sense a golden opportunity. Masterminded by college-aged Ki-woo, the Kim children expediently install themselves as tutor and art therapist to the Parks. Soon, a symbiotic relationship forms between the two families. The Kims provide "indispensable" luxury services while the Parks give the Kims a way out of their shabby circumstances. But this new ecosystem is fragile, and soon enough greed and class prejudice threaten to upend the Kims' newfound comfort.
