All the usual suspects are all here. Carol Henderson (Linda Blair) is the good girl. Erika (Sybil Danning) is the HBIC. Duchess (Tamara Dobson) is the rival leader. Val (Sharon Hughes) is the tough veteran who befriends Carol. Bubbles (Louisa Moritz) provides comic relief as the crazy/dopey girl. Edy Williams plays the nympho, Julie. Henry Silva appears as Lester, the outside drug connection. He is also quite skeevy.
Despite its adherence to formula, Chained Heat throws you some curve balls. The bad guys are always scheming against each other, particularly where the drug running is concerned. Everyone is playing sides in Corrections, while the prisoners tend to play things normally. I think it gives the film an edge over a lot of it's competition. Also, much of the sadism is not shown. It is often easy to make up for lack of story with gratuitous torture. This is also one of the better Sybil Danning films I have seen. She gets to keep her clothes on, for the most part, and plays tough in a less over-the-top fashion than usual.
I am going to rank this among my WIP favorites. If you can find it, it is worth the watch.
