Tomishima Heita has worked for a mid-sized construction company for the past 4 years. He is sincere and enjoys working with construction sites. One day, he is transferred to the business affairs department. The role of the business affairs department is to obtain contracts with large organizations like public utilities. The department is jeered by other workers and often referred to as the collusion department. Workers in the business affairs department struggle to win a 200 billion yen public works project. Is collusion a necessary evil? Heita agonizes over this question. Nevertheless, he begins to enjoy his work and his company takes the lead in winning the large contract. Meanwhile, a special prosecution team looks into corruption involving politicians and Heita becomes a target. (Source: AsianWiki)
