Unfortunately, his grades are failing and he is on the verge of being kicked out. Max wants nothing more than to stay in Rushmore. When Mr. Blume and Miss Cross fall in love, Max goes on the warpath to revenge. That's about all the plot there is. We see his wild attempts at wooing the much older teacher, and his wicked revenge on his friend Blume.
Every scene is set in a different location, with some kind of new activity going on.
The effect is that the story becomes an unreality, like a weird cartoon. It's all a bit overwhelming, and the obsessed Max is hard to connect with. Murray, on the other hand, delivers a strong sad-sack performance, and his long face tells volumes. Whatever its minor shortcomings, Murray is a shining star, and you should see the movie just for him.
