Radiant yoga instructor MAY (Jessica Biel) has her wholesome life thrown out of balance by the arrival of her long-lost biological sister SHIVA (Zosia Mamet of the hit HBO show GIRLS), a street-smart yet naïve young woman with an abusive boyfriend. May feels compelled to rescue the hapless Shiva and finds herself increasingly drawn out of her sedate world and deeper into Shiva's chaotic one with lethal consequences.
