Molly always knew there is something her parents were keeping from her most of her life. She could hear her parents talk in whispers and when she enters the room they go silent and exhange glances. Every birthday, or holidays, Molly's parents are always sad and lost in grief, but Molly never would have imaged the dark painful secret they have been keeping from her. One day Molly finds a old photo album hidden away in her parents closet when she was looking at her mom's dresses. She flips through the pages, she sees her baby pictures with another baby girl next to her named Holly, her twin sister. Feeling betrayed and frustated, Molly confronts her parents. They finally reveal the truth. Holly passed away at the age of two from a blood disorder with no cure.
Unable to cope with the loss, Molly's parents decided to keep her memory alive by pretending she never existed. Molly made both her parents realize that Holly may be gone, but she will always be part of her just like she will be her parents. After that, Holly's memory is cherished and she will always be part of their family.
