On a river deep in the Mexican jungle stands the colossal villa Xanadu, a wellness center that's home an ardent spiritual group devoted to self-help guru Paul Bentzen and his enigmatic wife Kali. But when Paul mysteriously dies, his entire estate--including Xanadu--is left not to Kali, but to his estranged niece Sveta. Shocked and confused, Sveta travels from New York City to Mexico to pay her respects. At first, Xanadu seems like a secluded paradise with its tumbling gardens, beautiful people, and transcendent vibe. But soon the mystical façade wears thin, revealing a group of brainwashed members drunk on promises of an impossible utopia, guided by a disturbing belief system and a charismatic, dangerously capable leader. As the sinister forces surrounding Sveta become apparent, she realizes, too late, she can't escape. Frantic and terrified, she discovers her only chance of survival is to put her confidence in the very person she trusts the least.
