The guest

Iris and Gabriel have just got home from a make-or-break holiday. But a shock awaits them. One of their dearest friends, Laure, is in their house - sleeping in their bed, wearing Iris' clothes, even rearranging the furniture. She has walked out on her husband - and their good friend - Pierre over his confession of an affair. Iris and Gabriel want to be supportive. But as Laure's mood becomes more unpredictable, her presence begins to unravel secrets in all their pasts - until things inevitably reach breaking point.
