Evil wedding guest Louise Lee finally gets hers! Louise, in her beautiful mother of the bride outfit, is thrown in the gungetank and thoroughly gunged, before being removed and facing treacle, black paint, ice-cream sauce, cake and more. After a brief recap of the first 2 parts where bridesmaid Adriana, and bride Nikki were thoroughly trashed by Louise, their bridesmaid dress, and wedding gown utterly destroyed, we resume the story.

Adrianna is able to provide proof that Nikki never slept with Louise's boyfriend, and this turns Louise's offscreen evil henchmen against her. They will no longer protect her... instead they encourage Nikki and Adrianna to get some revenge.

and boy do they! Gunged then totally trashed with assorted mess, her lovely outfit ruined... Louise is left completely destroyed.
