After their mother dies, Celeste Hart struggles to come to terms with her own identity, literally, as her mother was the only person who could ever tell Celeste apart from her identical twin, Leeann. Dealing with grief differently, Celeste begins to pull away from her sister, her partner in life and business, while dangerously unstable Leeann only smothers Celeste more. Mere days before opening their hip new yoga studio, Celeste escapes on a self-realization yoga retreat led by Sergio, a Yogi who's as charming as he is spiritual. Abandoned, Leeann unravels maniacally and plots to find her twin and put an identity-bending end to Celeste's new beginning - at any cost.
