Elise, a successful businesswoman, finds her life spiraling into chaos when she discovers a doppelganger, Lila, who is living a parallel, darker life. Elise becomes entangled with Lila, and begins to question her own identity and sanity as the lines between reality and fantasy blur. She learns that Lila is not just a reflection of her own fears, but a product of a secret organization, The Collective, that manipulates individuals with "abilities" for their own sinister purposes. The Collective has been tracking Elise for years, experimenting on her and creating Lila as a means to control her power.
