Basically the Silver Surfer is searching the universe and contemplating the meaning of life and everything. Some organ pirates try to get him. As soon as he's about to vaporize the pirates, another ship appears that send them running. The ship is from a "galactic " type United Nations and they talk of how they live in peace and harmony. Silver Surfer is of course intrigued and tags along to see what's up.
That's the outline, but believe me. it starts to get heavy! Lots of twists. Like I said, I'm only on issue 2. The story is very interesting, but I would recommend it for the art alone! Visually stunning stuff - not your ordinary Marvel art.
