It’s been 21 years since I saw it, but from memory…
There’s a guy with a regular job, Keanu (called Neo in the film). Does some hacking in his spare time. Has hacker friends.
He’s bored one night so goes to a club and meets up with some of them. They’re all bigging up a mate of theirs who is a really good hacker, won’t say his name. Eventually agree to give him his number.
Neo texts him and is like “I hear you’re good at hacking” and the number replies with “who dis?” and Neo tells him and the person agrees to meet.
Then Neo gets mobbed when he leaves the club, but manages to get away because Laurence Fishbourne is there and is pretty handy. He takes Neo to a shared office space he’s been hiring. His name it Morpheus.
They have a little chat, but during the chat Morpheus is all coy about this big secret he has, casually dropping it into conversation but is all like “oh no, I can’t mention that though”, blatantly trying to get Neo to ask more about it. Neo asks some clever questions and eventually Morpheus is like “I’ve got a big secret but rather than tell you, you’ve got to decide whether to eat a red or a blue jellybean”. Neo is like wtf? but too intrigued to pass it up. Morpheus says that the red bean gives you the truth, and the blue one is just tasty and nothing changes, but you get to have a jellybean. Naturally Neo eats the red one.
CGI scene where stuff gets weird, then cuts to Neo waking up in what looks like some sort of cryo machine, and he’s all naked and ripped. Gets out and is like “wtf is going on?!” when a bunch of people congratulate him for leaving the matrix. He doesn’t recognise any of them, and his junk is on screen for a good 5 minutes, with close ups and everything. He has a chat with them, and they explain that he was in the matrix which is something that killer robots made to keep humans happy while they used them like batteries. Neo is like “wo” but seems to believe it all despite how far fetched it is. Then one of them who isn’t in the conversation casually does that thing where they stab a knife in between their fingers really fast and Neo is like “wo, you are really good at that?” and the guy is like “Oh, that? You just need an upgrade” and they plug Neo into a machine and update his O/S and now he can do kung fu and stuff. Then they tell him about how there’s a guy called Smith who wants to kill them and they need to protect the people who’ve escaped the matrix, and you can use those kung fu things now in the matrix if you ever want to go back in (though I’m not sure why you would).
So now Neo goes back in the Matrix but he’s like a badass and he’s there with a female character who it seems he’ll inevitably fall in love with. She shows him he can jump really far and stuff and they jump from one building to another. Basically there’s a really long montage of Neo being in the world but now with cheat codes.
Then they bump into Smith who is in sunglasses and is clearly also using cheat codes. They get in a tussle and the female character dies. Neo swears to avenge her death. Then he leaves the matrix and tells the others what’s happened, but now the female character is dead irl too for some reason.
Then there’s a load of scenes with Neo fighting Smith, but losing and just getting away, with more training montages in between, then at the end of the film, it’s like the end of karate kid and just as Neo is about to die, he kicks Smith in the face and kills him (so he thinks) and now he’s so good at training that he can stop bullets in midair. Then it ends.
