Okay kiddo, so there's this movie called Crimson Tide and it's about a really important job that some people have in the Navy. They work on a big submarine that goes really deep in the water and has powerful weapons on it.
The people on this submarine have to be super careful and follow very specific rules when they use the weapons. If they don't follow the rules, they could start a war that could hurt a lot of people.
In the movie, there are two important people who have different opinions on what to do in a certain situation. One guy thinks they should use the weapons, and the other guy thinks they shouldn't.
This causes a big argument on the submarine and everyone has to figure out what to do next. It's really intense and exciting to watch, but it also shows how important it is to think carefully before making big decisions that could affect lots of people.
