Pareto no Gosan ~ Caseworker Satsujin Jiken

Makino Satomi (Hashimoto Ai) has been reluctantly working for the welfare division at a municipal office. One day, she is ordered to be a caseworker all of a sudden and this makes her feel uneasy. A veteran caseworker named Yamakawa Toru (Wada Masato) encouragingly tells Satomi that it is a rewarding job. Together with a colleague called Onodera Junichi (Masuda Takahisa), Satomi starts engaging with people despite her doubts. However, a few days later, Yamakawa's murdered body is later found after an apartment fire. Why would this happen to someone so adored by the people he has helped? As suspicions of Yamakawa's possible involvement in something illegal grow, Satomi and Onodera begin to get entangled in the lives of various people over life insurance and the shadow of impropriety hanging over the town.
