Jo St-Clair is a veteran detective in Paris' elite Criminal Brigade, tackling the city's most challenging murder cases. Brilliant and brutal, St-Clair must outwit pathological killers to solve the most shocking murders, all while juggling a personal life just as challenging and as dangerous as the cases he solves.

The series (formerly known as "Le Grand"), shot in English entirely on location in Paris, stars Jean Reno as Joachim "Jo" St.-Clair, a veteran French detective tackling the city's most challenging murder cases, each tied to an iconic Parisian location, including the Eiffel Tower, Notre Dame and the Catacombs. Emmy-winning producer René Balcer ("Law & Order", "Law & Order: Criminal Intent") serves as the showrunner of "Jo", which he created with Malina Detcheva and Franck Ollivier. Directors of the first season include Charlotte Sieling ("Bron/Broen" a.k.a. "The Bridge"), Stefan Schwartz ("Dexter") and Kristoffer Nyholm ("Forbrydelsen" a.k.a. "The Killing").
