François Sentinelle leads a double life. During the day, he is the most media-exposed cop on the Island of Réunion, known for his tough methods and floral shirts, chasing criminals in his famous yellow Defender. But outside of working hours (and often during them), Sentinelle has another profession: variety singer. All Réunionnais have danced to "Le Kiki," his youth's hit song, which is now somewhat embarrassing. For the past fifteen years, he has been trying to regain success by preparing a new album... without success. However, Sentinelle doesn't want to choose between the police and music. While he remains busy with his concerts and the release of his album, a wave of violent crimes shakes the island. A prominent figure from the local elite is kidnapped, and another one is murdered. For any cop, it would be the case of a lifetime. But Sentinelle, completely absorbed in his music, doesn't really have the inclination to investigate.
