Our intrepid wire service reporter Carl Kolchak always gets the interesting and bizarre stories. In this one the plot must have been taken from the Walt Disney classic cartoon feature Ichabod Crane where Bing Crosby sang about not being able to reason with a headless man.
A headless biker known back in the Fifties as the Swordman is back with nothing above the neck and wielding that sword to decapitate some of his old biker crowd. They either participated in or witnessed his decapitation and he's taking a few heads of his own.
Darren McGavin along the way meets such interesting folks as Jim Backus the motorcycle dealer, historian Jay Robinson, and Larry Linville as Frank Burns giving up medicine and joining the police force and Jesse White a most insecure security guard.
The old biker gang is represented by Art Metrano and Sharon Farrell. It's always the colorful folks McGavin meets along the way in his investigations that made Kolchak: The Night Stalker the cult classic it has become.
