Essen Corporation is a large French company with 90,000 employees. One day, a financial analyst named Dama jumped from the top floor of the company's headquarters and ended his life. When the Ministry of Labor intervened to investigate, Emily, the manager of the human resources department, said that Dama's death was purely due to "personal factors". Only Emily's secretary knew that Dama's application for transfer was rejected. She had contacted Emily many times, but was repeatedly ignored. Labor inspector Mary is responsible for protecting the occupational safety of 30,000 employees in 2,500 companies. She is convinced that Dama's choice to commit suicide at work is a warning. She discovers a corporate management law called "Ambition Plan" in Essen, which aims to force 9,000 employees to resign voluntarily through transfers without "layoffs". If it can be proved that the human resources manager tried to force Dama to leave, Emily will face charges of "workplace bullying" or even "manslaughter". When the top management of Essen decides to put all the blame on Emily, how can the shrimp fight against the giant whale? How should Emily fight back?
