In the near future, Paris is divided into three zones that separate social classes, and no one can escape ALMA, a predictive AI that has revolutionized law enforcement. When ALMA’s creator is assassinated, Salia, a top agent, and Zem, a jaded cop, are forced to work together to solve a murder that may expose the dark secrets of the system they serve.

Guillaume Roussel composed the original score for Chien 51, directed by Cédric Jimenez and starring Gilles Lellouche and Adèle Exarchopoulos.

Guillaume Roussel is represented by the Grande Ourse talent agency.
