When an escaped convict, an anxious bride, a scheming new husband, and a suspicious attorney all convene at Grandpa's house--it doesn't take long for Grandpa to realize he has to reschedule his golf game. This lively combination of uproarious comedy and terrifying murder mystery revolves around the uncanny resemblance between escaped convict Tony and recent bridegroom Prescott (both played by the same actor). Newlywed Ashley's desperate attempt to figure out who is the real murderer is sometimes helped and sometimes hindered by her golf-fanatic grandfather and a mysterious visiting attorney named Muriel.  As the suspense mounts and the violence intensifies, Ashley slips into increasing hysteria, Muriel discovers the murderer's evil agenda, and Grandpa, drawing upon an unsuspected hidden reserve of inner strength, fine-tunes his stroke.
