Hoarding: Buried Alive

Doug and Darlene haven't let any strangers inside their home for the past 20 years, and there won't be party invitations any time soon considering their latest setback.

On Sunday's Hoarding: Buried Alive, we see inside the couple's house, which features piles of trash and one rather glum-looking cat. Four months ago, however, their lives became almost unbearable when a septic tank overflowed, tainting everything with filth and fecal matter.

"I'm not going to commit suicide," said Darlene. "However, if anything would drive me to that, this would be it."
