While chasing a taxi driver, he ends up drowning the patrol car and as a result enters into a skirmish with the city police.

Gibert informs the team about a "gang of Italians", who use two powerful Ferrari for committing their crimes, and instructs Marot to arrest them.

Alain, a colleague of Marot, tells the newcomer about the legendary taxi of Marseille and about the adventures of Daniel and Emilien.

Sylvain and his team find Daniel's nephew, Eddie Makhlouf, who was the taxi driver he was chasing.

As the thieves are escaping, Gibert makes a mistake leading to a car pile-up, one of the victims of which is revealed to be the Minister he had met previously.

One of the robbers, Tony Dog, a former driver for Formula 1, offers Sylvain a job and invites him to a private party.

Eddie, disguised as a waiter, enters Dog's office and finds the plan for the next robbery - the theft of a diamond "Cassiopeia".

The cops commandeer a civilian vehicle, but they eventually get stopped by the municipal police while the robbers continue their pursuit of the taxi.
