Given the question: Build a movie plot around this: Who is the group's latest subject after helping Lucie and Sarah? Anna
The answer is:
Lucie (Jessie Pham), who has been missing for over a year, is found hysterical by the side of the road. She leads police to the derelict slaughterhouse where evidence suggests she was held captive. Although there is no evidence of sexual abuse, Lucie bears the signs of repeated injury and neglect. Traumatized and uncommunicative, Lucie is unable to tell the authorities anything further about her time in captivity or the people who kept her there.Over time, Lucie makes friends with Anna (Erika Scott), another girl in the youth home where she lives. Anna looks after Lucie and eventually gains her trust. Lucie appears to be haunted by something or someone - a shadowy, rasping female figure (Isabelle Chasse) who apparently mutilates Lucie. After one such episode, Lucie makes Anna promise not to tell anyone about the creature haunting Lucie. Meanwhile, with the help of the doctor (Tony Robinow), the police even questions Anna, so as to know whether Lucie has communicated something to her. Anna says that Lucie cannot usually remeber anything about her captivity period.At this point, the film moves ahead 15 years, and shifts its attention to the Belfond family. Mom (Patricia Tulasne) is fixing a sewer line in the yard, Dad (Robert Toupin) is making breakfast, and son Antoine (Xavier Dolan) and daughter Marie (Juliette Gosselin) are wrestling over a love note Antoine received. As everyone sits down to breakfast, the doorbell rings - it's Lucie (Mylene Jampanoi), who shoots the father to death with a shotgun. The mother follows in short order, and then Lucie hesitates, asking Antoine how old he is and if he knew what his parents have done. When she doesn't get an answer, she kills Antoine. Marie hides upstairs, but Lucie finds her and kills her as well. Panicked, Lucie calls Anna (Morjana Alaoui) at a public phone to come and help her. Lucie claims she has "done it". Anna, shocked at hearing what Lucie says asks if she's sure these are the people who kidnapped her. Lucie confirms and they complete their phone call....
