Landmarks

Dom Cobb and his partner Arthur perform an illegal corporate espionage by entering the subconscious minds of their targets, using two-level "dream within a dream" strategies to "extract" valuable information. Each of the "extractors" carries a "totem", a personalized small object whose behavior is unpredictable to anyone except its owner, to determine whether they are in another person's dream. Cobb's totem is a spinning top which perpetually spins in the dream state. Cobb struggles with memories of his dead wife, Mal, who manifests within his dreams and tries to sabotage his efforts.

I met a traveller from an antique land Who said: Two vast and trunkless legs of stone Stand in the desert. Near them, on the sand, Half sunk, a shattered visage lies, whose frown And wrinkled lip, and sneer of cold command Tell that its sculptor well those passions read Which yet survive, stamped on these lifeless things, The hand that mocked them and the heart that fed. And on the pedestal these words appear: "My name is Ozymandias, king of kings: Look on my works, ye Mighty, and despair!" Nothing beside remains. Round the decay Of that colossal wreck, boundless and bare The lone and level sands stretch far away.
