Synopsis
John Wayne, in the last of his Civil War characterizations, portrays Cord McNally, a Union Army colonel who loses a gold shipment in a Confederate raid, during which a devoted young officer is also killed. After the end of the war, McNally bears no ill-will toward the leaders of the raid, Pierre Cordona (
Jorge Rivero) and Tuscarora Phillips (
Christopher Mitchum), who were acting as soldiers, but he still wants the two unknown men on the Union side who they say sold them the information about the gold shipments. A year later, McNally crosses paths with one of the men, now a deputy from Rio Lobo, who is about to take Shasta Delaney (
Jennifer O'Neill), a seemingly innocent young woman, out of a neighboring town at gunpoint. A shootout ensues, in which McNally's man and three other Rio Lobo deputies are killed, with help from Cordona -- this makes McNally very interested in what's going on in Rio Lobo, and he decides to go there with Cordona and Shasta. They find a whole community under siege from their own sheriff, a sadistic ex-outlaw named Hendricks (
Mike Henry). What follows is a series of confrontations and revelations that are alternately suspenseful, sadistic -- with maimings worthy of a spaghetti western and characters even getting blown to bits -- and even occasionally comical. But the pieces all tie together very neatly, despite a convoluted plot that's sort of
Rio Bravo (made 11 years earlier, also starring Wayne and directed by Hawks, and scripted by
Leigh Brackett) turned sideways and readjusted to a more cynical era. ~ Bruce Eder, All Movie Guide
