Horror author Jill has just moved to suburban New Jersey, hoping to fit in with the new PTA moms and maybe not weird everyone out with her Final Girl coffee mug. You know. Make some real friends. But then a plastic face-masked serial killer begins slashing their way through town, one overly made-up mom at a time. The police are incredulous. The moms are indignant. And Jill is slowly wrapped into a killer’s murderous spree, until she might just be the last woman standing.
