In 1999, in Melbourne, the Babers are a happy middle-class family, and the fifteen-year-old ballerina daughter Rachel Barber is in love with her boyfriend Manni, who dances with her. One night, Mr. Barber is waiting for Rachel at the tram station, but she never appears. On the next morning, Mrs. Barber and he go to the police to report that their daughter is missing, but the police detective does not give much attention, believing Rachel is a runaway home. However, Mr.& Mrs. Baker do not give up and distribute missing person pamphlets along the tram route. Manni discloses to them that Rachel had been invited by an older woman for a confidential job to earn a great amount that would allow Rachel to buy the desired ballet slipper. Meanwhile, the unstable teenager Caroline Reid Robertson, who has inferiority complex, low self-esteem, depression and eventual seizures due to the medicines she must take, sees Rachel and Manni making out in a bench on the street. She was a former front door neighbor to the Barber family, with divorced parents, that idolized Rachel and tried to imitate her. Her obsession increased over the years, and she plots a plan to lure Rachel and bring her to her apartment. What will happen to Rachel?—Claudio Carvalho, Rio de Janeiro, Brazil
