Basically, a 32yr oldcel mentalcel with a low IQ due a mental condition. He works a minimum wageslave job where his co-workers constantly bully him and make fun of him. He’s offered to undergo a new medical procedure from the special needs school he goes to, experiment previously done on a mouse named “Algernon.”
He participates and very rapidly his IQ and memories begin increasing. Eventually he becomes so smart that’s he’s basically autistic and begins arguing, fighting and debating things with his superiors, he also loses his job and what not.
He develops a oneitis crush on his teacher too. Eventually, as with the mouse, the newfound intelligence begins regressing and he’s aware of this. He’s aware he’ll be back to his low-IQ retarded self. As he regresses down to normie-tier intelligence, the teacher takes him to his room in the basement, they kiss, and presumably they fuck.
One thing to note - the actor playing the character seems like a real Chad, and you see it more as he becomes less dumb.
Eventually he’s back to his retarded self and it appears he’s forgotten most things, especially the relationship and fuck with his teacher, so you can say it’s as if it never happened. He talks to her one last time in his retarded self, and she’s crying as she no longer sees the Chad he once was. All he wants her to do is place flowers on Algernon’s grave since the mouse died.
He also gets his old job back, and the co-workers go back to treating him like shit and making fun of him. He jestermaxxes at his own expense in front of his co-workers to fit in. He trips himself and makes himself a laughing target for his “work friends and boss” because that’s what life is all about, I guess.
