Steve finds much of the cash he was burying strewn by the wind or his dog Eddie, but worries more over rogue ex and CIA Greer being trackless. Five-0 investigates the disappearance of vacationer Jack Teague, who was dragged out on a single parachute mid-flight from the mainland by the impostor who to that end killed the real U.S. Marshal. Steve sends Danny to lead the search party for Teague in the jungle, where his rescuer/abductor is found murdered, himself researching from HQ to discover Jack is actually a Chinese sleeper agent whom Peking ordered eliminated. Agent Greer's suspended former CIA partner conducts his own parallel investigation, revealing to Steve she still works with the Chinese spies, leading their armed party in the jungle, where fights occur before Five-0 can arrest her, still refusing to help Teague, whom Miller picked up at his peril. Tani begs her training instructor at the Police Academy to informally run ballistics on Adam's sister's murderer's gun, despite her frustrating record.
