Diamant 13 is a 2009 French-Belgian-Luxembourgian film noir co-written and directed by Gilles Béhat. The screenplay is based on Hugues Pagan's novel L'Étage des Morts. The film was nominated for a Magritte Award in the category of Best Original Score for Frédéric Vercheval in 2011.
Mat is an aging, worn police officer. One day he is present when a criminal takes a female hostage in order to use the woman as a human shield. Mat refutes this strategy by shooting the man dead. The hostage remains unharmed but Mat knows all too well his action could have gone awry very easily. So afterwards he throws up and indulges himself to binge drinking. His constant enervation and his alcoholism have rendered him unacceptable as a law enforcer. When he is about to get sacked a former buddy contacts him. Franck has switched sides a long time ago and feels Mat would now be ready to condone this. But in spite of his misery Mat hesitates to become a drug trafficker. As fickle as he is it can work out either way.
