It’s 2017. Three defendants appear in court to be tried for the alleged murder of a garage owner who disappeared in 1996 in Magny-les-Hameaux in the Yvelines, not far from Paris.

It’s a crime that would not have been solved nor judged if there had not been another crime committed before.  Indeed, one crime can hide another.  This is the story of Fabrice Motch, the "Black Knight".
