Display posts of a specific tag in a page

Hi, I’m just wondering if there’s a way to display posts of a specific tag in a page? The page will display the first four posts in full view and the succeeding posts will be in the form of post titles.

Ex. I want all posts with the tag “news” inside the News page. The first four entries will be displayed in full view then the succeeding entries will be just post titles.

Can this be done using a plug-in or by modifying the template pages?
