Lock Up (1989)

 

 

With only six months left of his sentence, an inmate is transferred from a minimum security prison to a maximum security prison by a vindictive warden.

Tough prison camp thriller is watchable for its cast, but adds nothing new to the genre.
 

Halliwell (no star): "Nasty and sadistic, with no redeeming qualities."

Maltin*1/2: "Missing are Linda Blair, John Vernon, a lesbian guard, and 15 gratuitous showers; you do get a body-shop montage backed by Ides of March's "Vehicle." Bottom of the world, ma."
