Heat is a movie that was made a long time ago, in 1963. It's about a guy named Hank who's a thief, and he wants to steal a big pile of money from a bank. But there's a problem: there's a police detective named Mike who's trying to catch him!
The movie is called "Heat" because when people get hot and sweaty, they sometimes say that they're "feeling the heat." And in this movie, there's a lot of tension and excitement, so it feels like everyone is feeling the heat, both physically and emotionally.
The movie is very suspenseful, which means that it keeps you on the edge of your seat, wondering what will happen next. There are also lots of action scenes, which means that there's a lot of movement and fighting and other exciting things happening on the screen.
Overall, "Heat" is a movie that will make you feel excited and maybe a little scared, but in a good way. It's like a big roller coaster ride, but without the danger!
