Remove the text

Hi Guys

Sorry, was not sure how to name the title ??
Basically, I like to remove the content on the front of a post but when you click on it (where you go to the actual post itself) then the content should be there.

Lets say, under news section; you display 3 different news.
By default when you see the news section; you will see the title of each post as well as a brief summary about each post, right??

Now, how about removing that “brief section”
however, when you click on one particular post, then the content should be there …. hope I am making sense.

Any ideas ?!

Thanks
