Two police officers, Sakho and Mangane, meet during a drug deal and find they are complete opposites. However, their new commander, Mama Bâ, decides they would make great partners; their first case is the mysterious murder of a Belgian ethnologist.

The newly formed team struggles to work together as they discover that the murder might be related to the theft of an evil totem; between ritual object trafficking, migrant smuggling and drug trafficking, the investigation is proving to be eventful.

A ritual murder occurs at a luxury hotel which happens to be the territory of a gang known as the Toy Boys. Sakho, who is fed up with Mangane's methods, gets his revenge by ordering his partner to infiltrate the group in order to solve the crime.

Mangane's former best friend is savagely murdered. In order to help his distraught partner, Sakho takes over the case and follows the trail of a killer who seems to be impervious to bullets. Meanwhile, Mama Ba is attacked as part of a revenge-plot.
