Pacino plays Jack Gramm, a forensic psychologist whose testimony puts away accused serial killer Jon Forster (Neal McDonough). Jump to nine years later. Forster is about to be executed but a string of torture-rape-murders duplicating Forster's MO raise questions about whether the wrong man has been sentenced to death. Then Gramm gets a call telling him "tick tock doc" you have 88 minutes to live (I couldn't see my watch in the darkened theater but apparently the call comes at 20 minutes into the film so that the rest of the film plays out in pseudo real time). Suddenly everyone in Gramm's life becomes a suspect, bodies start to pile up, and the cops are seriously considering arresting Gramm.
