Lost: Every Man for Himself

SINOSSI

Sawyer discovers just how far his captors will go to thwart any plans of escape he and Kate might have when they forcibly and surgically implant a pacemaker in his heart which will detonate if he tries to escape again. Jack is called upon to scrub up in order to save the life of one of "The Others,", a team leader, named Colleen, who was shot by Sun during the theft of the sailboat. Meanwhile, Desmond's behavior begins to perplex Charlie, Hurley, and the rest of the survivors when he starts construction on an unknown device outside Claire's tent.
