Sheppard returns to Atlantis after a mission and finds the city abandoned, all systems dead -- and instead of ocean, sand dunes as far as the eye can see. 

"Like most season finales, this one will be big -- but very, very different."
(Photos at Joe Mallozzi's blog reveal an aged Rodney McKay featured in this episode, as well as a corridor filled with sand. The executive producer has also posted behind-the-scenes video of Colonel Sheppard struggling to make his way through a sandstorm in what looks like Atlantis itself. Looks like tomorrow will be a doozy that will see 'The Last Man' wrapping late, late, late -- or early, early, early depending on how you look at it. On tap: triage, battle action, on the bridge of the Phoenix.""I joined Marty G. and Paul for a special screening of 'The Last Man' director's cut. A great season-ender (and a bit of a tearjerker -- I defy you not to cry or feel sad or pity or slightly dizzy) with a final shot that will have fandom buzzing from final fade to the opening shot of season five." NEW! January 10 - "Watched the Day One Mix of 'The Last Man,' our Season Four finale. Great, great episode -- and one that will surely have fans pulling their hair out when those final credits roll. Hopefully, they won't have to wait too long for the Season Five premiere -- or there could be a riot. I love these types of time travel episodes in which the ultimate fate of our beloved characters are foretold -- some telling, others tragic, all touching. The last few episodes of Season Four should come with a 3-hanky alert."
