The Two Low-Budget Exploitation Crime Films Written and Directed by Some Guy Named William Martin Double Feature:
The Naked Road (1959)
Nineteen-year-old model is making out with an advertising guy in his convertible, but refuses to go to a motel with him. Maybe the fact that he openly admits he's married has something to do with it. Frustrated, he starts to drive her home but gets pulled over for speeding. The local Justice of the Peace fines him fifty bucks, then another fifty for contempt of court when he objects. To get the hundred bucks, he has to go back to the city, so the model is kept behind. (You'd expect him not to come back, but he actually does, albeit too late.)
A British guy who looks like a young Alfred Hitchcock with hair gets pulled in for speeding. (If you've seen the old commercial where the stuffy fellow complains about prunes having pits, gets one without pits, then says "They're still rather badly wrinkled, you know" followed by the slogan "Today the pits, tomorrow the wrinkles!" -- written by Stan Freberg -- then you've seen this actor.) He's actually in cahoots with the justice and the cop. He takes the model to some kind of diner, drugs her coffee, and keeps her prisoner until she agrees to work in "public relations" (i.e. prostitution.)
They try starving her, threatening to make her addicted to (unnamed) heroin, etc. Along the way, the British guy's assistant kills a "public relations" employee who got drunk and hit a client by dumping her out a window. He stupidly let another employee witness this, leading to the cops tracking him down and rescuing the model.
Mostly just talk in ordinary rooms. The director must have told everybody to speak slowly to drag out the running time. The two bad guys seem remarkably patient with their new slave. It's only when their tough-as-nails female associate shows up and suggests that they kill her that the tension builds a little, but by then the cops are outside.
Jacktown (1962)
Twenty-one-year-old punk with no job who hangs around with crooks is caught in flagrante delicto with a fifteen-year-old carhop. To the slammer he goes for statutory rape. The place is "Jacktown," the prison with the largest inmate population in the world at the time. (About 6000.) This was a real place, and we get some documentary footage of an infamous riot at the prison.
The punk gets harassed by other convicts, who don't approve of morals charges. Must be good, respectable folks. The warden takes him under his wing by having him work in his garden. The warden's adult daughter (Patty McCormack, famous as the little girl who kills people in The Bad Seed. The opening credits include the statement "starring Miss Patty McCormack," since she's the only big name in this thing) takes a shine to him.
For some reason, they send him to town with a guard and a convict who needs medical treatment. The ailing prisoner wallops the guard, so the punk runs away. (We're told later the guard killed the convict.) He goes to the warden's daughter in her apartment, where she convinces him to turn himself in.
There are also some scenes outside the prison of the punk's buddy robbing a grocery store and getting shot by the cops. If the first film was linear but slow, this one is quick but jumpy.
