Rescue Me alum Andrea Roth has signed on to play actress Catherine Oxenberg in the Lifetime movie, NXIVM Cult: A Mother's Nightmare.

Set to debut this fall, the film is based on the true story of how Oxenberg first introduced her daughter India (played by Jasper Polish) to the NXIVM sex cult, which was billed as a professional development and leadership group, then saved the young woman from physical and mental abuse.
