Nick, I mean Agent Nick, must find a 6000-year-old person (that's right, a 6000-year-old person). If you want to know if he succeeds or not, you have to watch the episode.
Agent Nick passes out in the middle of nowhere and gets dragged along the road for like, a good 3km. He also completes his final mission (for the time being, at least), which makes him go crazy and run around in public, screaming like a maniac.
In this episode, Agent Nick's missions take him on a wild goose--er, chicken--chase, to find a rooster whose call can be heard in three countries simultaneously. Oh yeah, he also has to find a shirt made of corn.
Agent Nick explores the automotive industry, of which Jilin Province is the leader in China. He sets out on a search to find a car that Chairman Mao has sat in before. Does he find what he's looking for? You'll have to watch the episode to find out.
