Emily also has a child, but her social status is far superior, and her work is busy all the time, not having enough to spend too much with her son. The boys of the two mothers are enrolled at the same elementary school, and through them the two mothers are quickly acquainted with each other. They confess each other and Stephanie admits that while she was adolescent, she slept with her stepbrother, and Emily complains of the professional failure of her husband, an English teacher. After a while, Stephanie finds out that Emily has disappeared and can not be found, and the authorities do not make much progress in the investigation, so she is trying to unravel this mystery.
