Clémence's grandmother suffers from Alzheimer's and has run away from her nursing home one too many times. What choice is there but to put her in chemical straitjacket? When this too much for Clémence to take, she kidnaps her grandmother and takes her on one last big trip to the childhood home she can't stop talking about. This impromptu trip will be an opportunity for Clémence to get closer to her grandmother, to better understand her illness, and to prepare herself for a grief that seems inevitable.
