Having killed Federal officer Doug Mercer, criminal Gerald Wilson (Robert Duvall) manages to escape an FBI dragnet. Hoping to make it to Mexico, Wilson forces a thief named Jack Collins (Burr De Benning) to act as his accomplice. To make certain that Collins cooperates, Wilson holds the man fiancee Carolyn (Davey Davison) at gunpoint throughout their tortuous southward ordyssey. While Efrem Zimbalist Jr. is still nominally the star of The F.B.I., the series' producers devoted more magazine ad space to this episode's "special attraction": namely, the new 1970 Lincoln-Mercurys (guess who sponsored the show?) ~ Hal Erickson, All Movie Guide
