Similar premise as “Clash of Fists.” We start with Nicky standing triumphant over a defeated Karina. Nicky then delivers an unrelenting beatdown along with multiple tasering, kills her, and then continues to beat her lifeless body. When then see the same scene play out again, but this time it’s Karina beating the hell out of Nicky.
In both scenarios, the Victim takes the beating without crying out or begging. She does some light moaning/groaning until she is knocked out and killed. The Killer is mostly quiet, maybe some light grunting, but nothing loud or over the top. No blood or bruising.
