Molly explains that a doctor has offered her a shred of hope - a monthly shot of an opioid antagonist, which prevents toxic substances from binding to the central nervous system. However, there's a catch - Molly must stay clean for four days to receive the promising treatment. Drama, starring Glenn Close and Mila Kunis
