How can I play a movie clip from library?

Hi, I’m quite new to flash and I’ve encountered a problem. I would like to know the actionscript for a button to play a movieclip in the library (which is a transition between pages, named “transition1”). However, I have not inserted this movieclip onto the stage in any frame. Is it possible to use actionscript to play this movie clip for its duration on top of the content and then get rid of it from view?
