The Majorettes (released in the United Kingdom as One by One) is a 1986 American slasher film directed by S. William Hinzman,[4] written and produced by John A. Russo, which he adapted from his own novel.

A camouflage-clad serial killer has begun mysteriously killing the members of the school's majorette squad under the guise of "saving their souls" before they reach adulthood.

The housekeeper and her son ambush the sheriff at his house, discovering that he is a religious fanatic that is murdering the majorette squad before they turn 18 so that they will stay pure and not become sinful adults who have pre-marital sex or do drugs.

In the confusion of Vicky's abduction, the sheriff turns the tables on his blackmailers: He murders Helga and destroys photographic evidence proving him to be the killer.

The Sheriff subsequently frames the now-dead Harry (who was killed by the biker gang earlier) for the murders, as he had a history of being a peeping tom.
