A police inspector, suspecting an attorney of two child sex murders, has him held for a questioning session that goes on for hours.

Inspector Gallien is investigating the rape and murder of two little girls. The only suspect is attorney Jerome Martinaud, but the evidence against him is circumstantial. As the city celebrates New Year's Eve, Gallien calls Martinaud to his office and interrogates him for hour after hour while Martinaud continues to maintain his innocence. We learn all about the evidence; we meet Martinaud's wife and learn all about the rift between the two; but will we, and Gallien, finally learn whether Martinaud is guilty?—Anonymous

As the horrifying news of the sexual assault and murder of two innocent girls terrorises a small seaside French town, the cryptic attorney, Jérôme Martinaud, is summoned to the provincial police station to testify. But, more and more, against the backdrop of New Year's Eve, Inspectors Antoine Gallien and Marcel Belmont find themselves grappling with half-baked leads and circumstantial evidence, even though, deep down inside, they are convinced of the lawyer's guilt. Now, over the course of a single rainy night, Gallien has to make Martinaud confess; however, in vain. And, hour after hour, Martinaud sticks to his story. Can Madame Chantal Martinaud shed some light on the conundrum of the double homicide?—Nick Riganas
