Wash Away.

Kana is a young woman working in a soapland. When her mother suddenly gets hip surgery, Kana needs to spend a week juggling both her soapland job and taking care of her elderly grandmother she hasn't seen in years. Her grandmother can't remember her anymore due to her dementia, and as Kana washes men by night and her grandmother by day, she keeps wondering if there's any point in making an effort to connect with her.
