When Rick Shepherd, a physician, approaches his office on a busy Manhattan street, he finds police cars, an ambulance and crime scene technicians. He soon learns that a passerby was shot three times in the back, murdered at the front door to Rick’s office. Later that evening, while watching the local news, Rick and his fiancee, Jackie, see a photo of the victim --- to their horror, the deceased looks identical to Rick. Two nights later, Rick’s father is shot and killed in the exact same way. Detectives Art Nager and Liz Callaghan launch an investigation. There are no clues leading to the perpetrator. Even more ominously, someone has been calling Rick and Jackie’s apartment and hanging up. Whoever is targeting Rick must have murdered his father, and they now have Rick in their crosshairs.
