Jérôme is a speech therapist, dispatched to help the care home's ageing population snatch and hold tight on to the speech still afforded to them. But Michka is no ordinary client. For Michka is haunted - by strange figures who threaten to unearth a secret, buried guilt that she's carried since she was a little girl. And she is losing her words - grasping desperately for what once came easily so to her. Michka doesn't know how to repay her debt - and as her words slide out of her grasp, time is running out.
