A cameraman, Ron Kobeleski (Dylan Haggerty), finds out that his next-door neighbor, Walter Ohlinger (Raymond J. Barry), may be the much-fabled second gunman who assassinated President John F. Kennedy. At first, Kobeleski doubts the elderly man's story. But Ohlinger increasingly convinces the younger man that he was a pivotal player in one of the 20th century's most notorious crimes. Kobeleski eventually follows Ohlinger to Dallas and elsewhere, searching for the agent who trained him to kill.
