Cool Hand Luke is a movie about a man named Luke who does things that make him very cool. He is very strong and can eat a lot of eggs, which people think is amazing. But, sometimes he does things that make people upset, like breaking the law.
Because he breaks the law, Luke has to go to something called "jail" which is like a timeout for grown ups. In jail, he has to do things that are very hard, like dig holes and carry heavy things.
The people who run the jail try to make Luke do things they want him to do, but he doesn't always listen. He keeps doing things his own way, even if it means getting in trouble.
At the end, something sad happens to Luke and he has to go away forever, but people remember him as a really cool guy who did things his own way.
