Marie and Gordon claim that a neighbor has been attacking their house with noxious fumes, causing it to be completely unlivable and making them sick. Marie’s daughters, Amy and Emily, say their mother and Gordon are taking “extreme measures” to prove a neighbor is responsible for the alleged poisoning– including making daily diary entries and constantly monitoring surveillance cameras mounted around their property.

A comprehensive chemical analysis performed by a company specializing in the detection and mitigation of environmental contaminants determines that their house is not being contaminated by chemicals from neighbor, but instead, by a toxic mold growing inside the couple’s home.

“There is a neighbors’ dispute, and that’s not going to go away just because we’ve come on ‘Dr. Phil,’” says Marie after hearing the results of the test at her home. “There’s things that are happening around our house that – unless you live there – you can’t see.”

What is Marie’s response when Dr. Phil asks her if she accepts the results of the environmental analysis?
