FBI Agent Lou Schein is assigned to investigate a grisly murder in Los Angeles, one echoing a similar case in Phoenix, Arizona. Agent Schein, a golf enthusiast, notices a strange coincidence: both crimes occur while the LPGA tournament is being held in the respective cities.
After the fourth murder, it's clear they are after a serial killer obsessed with the golf game of match play. He is scoring the individual murders as one hole of the match on the current tournament course.
The killer leaves a series of taunts and clues which the FBI must decipher to learn where he will strike next. It is a game that becomes an obsession for both the killer and Agent Lou Schein, one determined to win the match and the other to stop him before he strikes again.
