Then she finds that their bank accounts have been left practically empty. She feels she doesn't know who her husband was anymore.
Jerry Hobart was hired to kill Phil Kramer and did so. Now he's been hired to kill Emily, but he figures there must be an interesting reason behind the job and grows curious.
Emily is also struggling to find reasons for Phil's death and his actions and as they both struggle toward answers, they become entangled for a time in each others' lives.
