A Mafia boss and his family are relocated to a quiet town in France under the witness protection program after snitching on the mob. Despite the CIA's best efforts to ensure they blend in and adopt a low profile, the family struggles to shake off their ingrained mobster habits. The father, trying to write his memoirs, deals with the frustration of a writer's block while grappling with the pent-up aggression of his old life. The mother navigates the challenges of managing the household in a new environment, confronting local disrespect with unexpected ferocity. Their children, a son, and a daughter, each face their own battles at school, applying unconventional and often violent solutions learned from their parents to deal with bullies and teenage romantic woes. The peculiarities of their past lifestyle make it difficult for them to adapt, causing comic and chaotic brushes with the norms of their small French town.

As the family's attempts to fit in become increasingly disastrous, their past catches up with them. The Mafia, seeking retribution, begins to close in on their location, precipitating a series of events that threaten to expose and endanger the lives of the town's residents. In their fight to protect their new identities and lives, the clash between their attempts at normalcy and their innate criminal instincts creates a volatile environment. The family's cohesion and loyalty to each other become their greatest weapon against the impending danger, blurring the lines between their old and new worlds in a frantic struggle for survival.
