 A tale of obsession and deception, and the struggle for love and faith in a world where both seem impossible. The film charts the emotional and physical hothouse effects that bloom one summer for two young women: Mona, behind a spiky exterior, hides an untapped intelligence and a yearning for something beyond the emptiness of her daily life; Tamsin is well-educated, spoiled and cynical. Complete opposites, each is wary of the other s differences when they first meet, but this coolness soon melts into mutual fascination, amusement and attraction. Adding volatility is Mona s older brother Phil, who has renounced his criminal past for religious fervor - which he tries to impose upon his sister. Mona, however, is experiencing her own rapture. "We must never be parted," Tamsin intones to Mona but can Mona completely trust her?
