Even if you've seen a lot of movies about class struggle, you can bet you've never seen one like Parasite. From director Bong Joon-ho, it tells the story of two families, one with a lot of money and one that's just struggling to get by. Parasite won the top prize, the Palme d'Or, at this year's Cannes Film Festival, and it's South Korea's entry into this year's Oscars race.
