The game begins with an unconscious, wounded stalker (the player character) being brought to Sidorovich, a black-market trader operating inside the Zone of alienation (or simply "The Zone"). Sid is able to save his life, but the wounded stalker is amnesic; the only clues to his identity are a tattoo on his arm of the acronym "S.T.A.L.K.E.R." and his PDA which contains only one entry in the to-do list: "Kill Strelok." The amnesiac stalker is dubbed "Marked One" by Sid.
