Some people have bad days. Henry Altmann (Robin Williams) has one every day. Always unhappy and angry at the world including everyone in it, Henry sits impatiently at the doctor’s office and is finally seen by Dr. Sharon Gill (Mila Kunis). Sharon, who is enduring her own bad day, reveals that Henry has a brain aneurysm. This news makes Henry even angrier, and he demands to know how much time he has left. Faced with Henry’s anger and insults, Sharon abruptly tells him he has only 90 minutes. Shocked and reeling by this news, Henry storms out of the office, leaving Sharon stunned by what she has just done in a lapse of judgment. As Sharon goes on a city-wide search, Henry struggles with his diagnosis, determined to make amends with everyone he has hurt in his life.
