Section de recherches
Section de recherches ("Investigation Unit") is a French television series that was first broadcast on TF1 on May 11, 2006.
In Belgium, the series was shown on La Une from November 9, 2013.
The Investigation Unit is a special unit of the National Gendarmerie, responsible for the most complex cases. In Bordeaux (from 2006 to 2013) and then in Nice (since 2014), it investigates child abductions, disappearances, vicious or sexual crimes. In search of witnesses, the team is empowered to extend its investigations beyond the borders of France.
The series was developed at the same time as another TF1 police show, "R.I.S, police scientifique", and so the production team chose to create points of difference between the two, opting to portray gendarmes outside of Paris, in Bordeaux, to present different scenery. The series has a deliberate focus on interpersonal relationships, inspired by American series such as "Cold Case" and "Without a Trace".
The show runner Dominique Lancelot is both producer and screenwriter. The series is one of the few French productions to be written using the writing room process commonly employed by American TV shows: the writers work in two groups to produce two storylines at a time and meet several days a week to work together. One of the writers is then designated to write the step outline, and another to write the dialogue. Each storyline thus passes through several hands before receiving the approval of the show runner for the shoot. The series is therefore in continuous production, with each episode being shot as soon as it is finalised, a style quite rare for French series which are more typically filmed in whole seasons. Each episode has a budget of €900,000, plus a €100,000 fee payable to the Centre national du cinéma et de l'image animée (the National Centre for Cinema and the Moving Image), making a total cost of one million euros per episode.
In 2013, following the seventh season, the production team decided to make a number of changes to the show, including moving the police unit from Bordeaux to Nice. Both technical and creative factors were cited as prompting the changes; the writers wanted to develop the serial format of the show, with an increasing focus on the characters' personal lives; and the at times inclement weather in the Gironde region had been creating difficulties in filming some of the show's many outdoor scenes. The milder climate and longer days in the Alpes-Maritimes made production schedules easier.
The show was commissioned by TF1 for a tenth series to be broadcast in 2016, but underwent a major upheaval when at the end of the ninth series producer Dominique Lancelot stepped down from her role as show runner and was replaced by Marie Guilmineau (The Shadow Men).
In 2008, Linda Hardy joined the cast of the third season as a Chief Warrant Officer Claire Linsky. She decides to leave at the end of next season series in 2010 to focus on his family.
In 2011, two new characters appeared in the fifth season: Warrant Officer Fanny Caradec played by Félicité Du Jeu and Officer Marc-Olivier Delcroix played by Vincent Primault.
The seventh season saw many casting changes. Félicité Du Jeu left the series because of her pregnancy, she puts her career on hold to give birth to a baby girl. Kamel Belghazi also left the series in mid-season. Manon Azem joined the show shortly after in the role of Warrant Officer Sarah Casanova.
In 2013, the relocation of the series from Bordeaux to Nice for the eighth season led to many changes in the cast: except for Xavier Deluc and Chrystelle Labaude and Manon Azem, all the other actors (Jean-Pascal Lacoste, Virginia Caliari and Olivia Lancelot) are written out. New joined as the new characters: Franck Sémonin in the role of Lieutenant Lucas Auriol and Julie Fournier in lieutenant Roxane Janin. Them joined also Stéphane Soo Mongo as Warrant Officer Alexandre Sainte-Rose and Félicité Chaton as Warrant Officer Victoire Cabral. Finally, Manon Azem returns to the cast in the eighth season to the fifth episode.
