The seemingly ordinary chicken shop owner's identity is suspicious. People think he just fries chicken, but he also helps resolve neighborhood disputes with ease. In truth, he was once a legendary negotiator. One day, rookie judge Jo Philip gets assigned to Shin Sajang's chicken shop, forcing Shin Sajang to take on an unwanted "parachute." Their approaches to justice-bending the law vs. strict legality-clash completely. But when Chief Judge Kim Sang-geun asks them to mediate a lawsuit over "maggot-fermented fish sauce," the two head together to Gangchun City.
