The Butterfly Room (movie, 2012)

Ann, a reclusive elegant lady, with an obsession for butterflies, is befriended by the eerily beautiful young Alice. Using her seductive innocence, Alice establishes a disturbing mother daughter relationship with Ann. Lured into her twisted world, Ann soon discovers that she is not the only recipient of the girl's affections. Confronted by Alice's other lady friends, Ann's shock awakens a dark, hidden past, unchaining a spiral of madness: a series of brutal and bizarre crimes that Ann will have to commit to preserve her harmless and deceptive appearances. The only one who recognizes there's something unsettling about Ann, is nine year old Julie, her next door neighbour's daughter. With the inevitable curiosity of a child, Julie begins to explore the corners of Ann's apartment, discovering a dark secret hidden in the walls of the forbidden butterfly room. No one believes what she's seen except for Ann's daughter. Horrified, she realises that the fate of the young girl lies in her hands.
