The CSIs find the dead body of a woman in her mother's home. The mother suffers from a condition called "hoarding" and has attempted to hide all her family secrets under piles of trash. The team is called in when a horrible stench is coming from the house in a downtrodden neighborhood. Once they arrive, they realize they have a hoarder on their hands. A woman who has lived under tons and tons of trash is found to also be hiding dead bodies. Awful family secrets are slowly uncovered by our CSIs and it is revealed that the woman's daughter had a darkside and had been killing young men so her mother, trying to save her from herself, chained her up and held her captive.
