Sunshine Dizon and Iza Calzado (left) are conjoined twins who grow up to be raised in different environments. One of them is naturally beautiful while the other becomes deformed. The time comes when one of them gets a new face and assumes a new identity, leading to conflict and revenge between the two siblings.

Sunshine and Iza became close with each other after working together in Kung Mawawala Ka and in Encantadia.

Iza Calzado plays the strong-willed Lara Carreon and the disfigured Sara Carreon. In a separate interview with PEP (Philippine Entertainment Portal), Iza said that her favorite person to work with in a drama series is Sunshine Dizon because she is like a mentor to her.

Sunshine Dizon plays dual roles in Impostora: Nessa, the spoiled brat cousin of the twins and Sara Carreon.

While the twins are growing up, a freak accident will scar one of the sisters' faces. Iza Calzado is the lovely face behind Sara's deformity.
