In the middle of the night, Antonin, one of Paul's best friends, calls him in a panic. His wife Cyrielle has disappeared, he is convinced that she threw herself off the bridge. When Paul arrives at the bottom of the bridge, he sees Cyrielle falling. He jumps into the water but it's too late, he can't save her. The gendarmes think quickly close the case. It is a suicide, Paul witnesses it. But Léa has doubts, why did Antonin contact Paul instead of calling the emergency services which were closer to the bridge? Would Antonin have manipulated Paul to disguise Cyrielle's murder as suicide?
