India Oxenberg, the 28-year-old daughter of actress Catherine Oxenberg, speaks out for the first time about her involvement in NXIVM and how she became a "branded sex slave."

The NXIVM curriculum gradually transforms India into a true believer.

India, as a member of the secret slave master group known as DOS, is subjected to forced starvation, sleep deprivation, multiple forms of abuse, and separation from family.

Catherine begins the fight of her life to expose the cult and rescue her daughter.
