Hellblock 13 (1999) is a low-budget horror film released by Troma and directed Paul Talbot. It stars Gunnar Hansen, Debbie Rochon, David G. Holland, and Jon Miller.
In a haunted death row cellblock, a deranged female serial killer reads a trio of twisted tales to her executioner. The stories all involve some form of supernatural horror but are otherwise unrelated.
The multi-part story structure is essentially a throwback, possibly an homage, to the vintage anthology horror films of British studio Amicus which were popular in the 1960s and '70s.
The spanking scene
In the second tale, "White Trash Love Story", a trailer-trash wife (Debbie Rochon) decides to get back at her bullying, abusive husband (David G. Holland) by using witchcraft. But things do not go as planned.
In a pivotal scene (36 minutes into the film) he berates her for not having his dinner ready when he comes home from work. After knocking her to the floor, he says "What this marriage needs is discipline", and whips her seven times with his belt. During the beating, she is hidden behind a kitchen counter so all that is seen on camera is the husband bending over her.
