Killer Wives (2019)

Chrissy Davis is the talk of the town following a very public mental breakdown and first-degree murder charge. She's quickly alienated by her high society friends and left alone to suffer in silence as she plots her revenge. An insanity plea grants Chrissy her freedom and she gets to work on her deviant revenge plan - whipping up a batch of mind-altering diet bars tailor made to bring out the worst in her backstabbing friends.
