Now this is a sleazy movie. It has everything!
Well, it has switchblade-wielding lolita gangs, a scene in a women's prison with a big scary lesbian warden, a shower riot, attempted rapes about every ten minutes, a gang leader wearing bright plaid pants with two-inch thick leather suspenders, a shootout at a roller rink, a miscarriage, and of course . . . murder.
Lace, the leader of the Dagger Debs, is played by Robbie Lee, who cannot act at all. It's an interesting effect, actually, since her attempts at menace are just like her attempts at seduction (and nothing like actual menace or seduction), so she comes off as something totally alien. She later went on to do voices in Rainbow Brite cartoons, for some reason.
The actual protagonist is played by Joanne Nail, who later played "Juggs" in the TV pilot version of the Racquel Welch vehicle Mother, Juggs & Speed. Did that make sense? If not, too bad. No time! My actual point is that she looks too old to be in high school, and her weird hairdo makes her look a lot like Amy Sedaris in "Strangers With Candy".
