Will Smith stars as Henry Brogan, a top-notch sniper and skilled combat fighter working for a black ops government agency named Gemini, performing one last kill before retiring from the assassin business at the ripe age of 50. He's the best at what he does but hates the man he's become, unable to even look at himself in the mirror without observing disappointment and pain. But just when he thinks he's pulling out, they pull him back in, discovering that he's been misled by his superior at Gemini, Clay (Clive Owen), in the nature of his latest assassination, making him feel betrayed. Along with fellow agent and his new ally, Danny (Mary Elizabeth Winstead), and his trusty pal Baron (Benedict Wong), Henry soon discovers they are trying to take him out as well, but with a younger, more agile, less angsty version of himself named Junior. Ang Lee directs this futuristic action-thriller.
