Display Post in a Page

I wouldn’t think this to be as hard as it is turning out to be.

I have a section in my header that is for Upcoming Events.
I would like to be able to make a post in a category called Upcoming Events and then the section of my site will show the latest post.

I have found plugins that show a LIST of the most recent posts, but I need to show the entire most recent post in a certain category.

If I need to describe this into more detail, please let me know.

Thanks in advance!
