Mark and Tamra enlist Cat’s help in lining up the audio in all four white tapes. She plays the resulting project for them, which causes Mark to pass out and injure himself. Now on their own, Cat and Tamra make a crucial new discovery: a secret code buried deep within the white tapes. After the two young women are startled by a strange visitor outside the front door, Cat leaves to break the code at home, but a bizarre accident threatens Mark and Tamra’s entire investigation.  See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
