Miranda discovers that she has a terminal genetic disease after fainting during a ballet lesson. While in the hospital, she sees another girl who looks identical to her named Ten. No one believes Miranda's claims except for her best friend Emma. Miranda later finds Ten again and Ten tells her that she was "made" for Miranda. Miranda's parents and doctors eventually confess that Ten is a clone created using Miranda's DNA as an insurance policy to donate organs to Miranda if needed. The doctors cloned Ten using the DNA of Miranda's deceased sister Jessica.
