19-year-old Ben Burns (Lucas Hedges) unexpectedly returns home to his family's suburban home on Christmas Eve morning. Ben's mother, Holly (Julia Roberts), is relieved and welcoming but wary of her son staying clean. Over a turbulent 24 hours, new truths are revealed, and a mother's undying love for her son is tested as she does everything in her power to keep him safe.
"The film is aware of the weight of its subject but loath to behave like an 'important' film—focusing instead on the specificity of one sick young man and the family that loves and fears him in almost equal measure." —Hollywood Reporter
