L'Homme de nos vies

Ariane, a nurse who had previously been unlucky in love, marries Amaury, a French-speaking Canadian surgeon. Camille puts her private life on hold to run her late parents' hotel. She gets involved in a passionate affair for several months with a regular guest, Nathan, a former trader. However, Nathan disappears during his last stay after emptying the hotel's accounts.

Camille continues her investigation into her ex, Nathan, who ran off with her hotel's takings; in Paris, Roman has a chance encounter with Agathe, Mathilde's daughter; Oriane becomes increasingly hysterical, eventually making a medical error and falling out with her best friend, Solenn; Iris, a pretty singer going through a divorce, meets Ghislain, an airline pilot.

Oriane is discharged from the psychiatric hospital with the help of Camille and Solenn; Roman and Mathilde's idyllic trip to Réunion does not go at all as planned; Iris is also on the island for a charity concert; Camille and Oriane gradually grow closer as they search for the man who deceived them.

Mathilde, having only just returned from Réunion, joins Agathe at the hospital, where Camille and Oriane are keeping watch over her; Iris has some big news for Ghislain that is set to shake him up considerably.
