When the criminal trio of the Clemens brothers murder the husband of Hannie Caulder (Welch), gang-rape her, burn down her house and leave her for dead, Caulder recruits bounty hunter Thomas Price (Culp) to help her get revenge by training her to be a gunfighter.
This film features examples of:
- Badass Preacher: The Preacher, appropriately enough, a skillful gunslighter.
- Big Damn Heroes: At the end of the film, when it seems that Hannie will meet the same fate as Price, the Preacher appears to shoot the knife out from Emmett's hand, allowing Hannie to kill him.
- Blasting It Out of Their Hands: When Emmett attempts to throw a knife into Hannie's back, he is thwarted by the Preacher, who shoots it from his hand.
- The Cameo:
- Christopher Lee as Bailey, a gunsmith who Hannie and Price task with building a special revolver for her. Lee's brief appearance in this film was his only role in a Western.
- Stephen Boyd as the mysterious gunslighter known as the Preacher.
- Everyone Calls Him "Barkeep": The Preacher is only known by that name.
- If You Kill Him, You Will Be Just Like Him: This is basically what Price implies when he warns Hannie that taking revenge will change her forever, and Hannie's reaction after he finishes the Clemens brothers implies that he was right.Thomas Price: Win or lose, you lose, Hannie Caulder.
- Mentor Occupational Hazard: Price gets killed by Emmett after parting ways with Hannie.
- Mentor Ship: It's implied that Hannie and Price fall in love with each other (see: the scene where they walk on the beach holding hands), Price being the one who teaches Hannie to handle a gun. Price dies before this can go anywhere.
- No Name Given: Whatever name the Preacher has is not known.
- Protagonist Title: Hannie Caulder is the protagonist of the film and lends her name to it.
- Rape and Revenge: The title character trains under a retired gunslinger to get revenge on three vicious outlaws who raped her.
- Terrible Trio: The trio of the Clemens brothers; Frank, Rufus and Emmett. They are very ineffective as bandits and most of their scenes derive humor from that fact.
- Vapor Wear: When she becomes a gunfighter, Hannie takes up wearing a poncho which barely manages to cover her most revealing curves, and clearly shows that she isn't wearing underwear.
- Vengeful Widow: Hannie takes revenge against the Clemens brothers for the attack that included her husband's murder.
