Rarely do I watch a movie and not know a single thing about it beforehand, but Parasite was one of them. It also just so happened that it would also be one of the weirdest movies I've ever seen, too.
The premise is simple. You've got yourself a typical low-standing Korean guy and his family. This whole family is constantly living off others' resources, even down to their neighbor's WiFi. The guy gets an offer through his friend to work for this wealthy family, as their daughter's tutor. Some stuff happens and he gets the job; then they draft a plain to aim to all get employed by this same wealthy family, and in doing so ultimately replace all the existing staff. Simple, right? Hence the name, "Parasite," because they're really just parasites trying to attach themselves to a host, and live a nice comfy life off them. So yeah, simple, really.
Slowly but surely they work their way through instilling a sense of distrust in the rich people's minds. First thing after the guy and the sister gets employed, the driver gets framed for using their car to traffic hookers and cocaine. Just like that, and the father is their next driver. Next up is the maid, who promptly gets set-up as having tuberculosis. Because, why wouldn't she? Right, anyway, now the mother is the new housekeeper.
After a long and arduous battle, they've finally managed to install themselves into their new home. They seems pretty satisfied after partying the better part of the day, drinking and feasting. It seems like they won and nothing could threaten their place. They've accomplished their goal of making the complete trust,
At one point in the middle of the night, while they're having a small party, feasting on the booze and treats the house has to offer, the previous housekeeper returns and asks to be let in, to fetch something she "forgot in the basement." This is obviously not part of the plan. So, what do they do when this obvious annoyance shows up in the middle of the night, asking to be let in, when the only one who's supposed to be in the house is the new housekeep – the mother in the family? They decide to let her in, obviously. Because why the hell wouldn't they risk letting an obvious liability in when they have literally no reason to do so?
The moment they let in the old housekeeper would also turn out to the the moment where things goes down the shitter real fast. Who could've known, eh?
Next, we have the obligatory sex-scene. Because of course we got to have one of those as well. Also, for the above picture, believe me I chose that caption for a reason.
