Smith is a man of rare gifts, including the ability to read minds. At the wedding of a reality-television celebrity he recently saved from kidnappers, Smith witnesses a group of gunmen open fire, hitting the bride and some of the guests. Although he is unarmed, Smith cripples one of the killers and is able to pry one word from his mind : "Downvote."
