Baby Mama.

Callie was a nurse at a hospital. She was single and always busy with work. Till she falls in love with a child abandoned at birth and under her care. The mother's family wouldn't accept an illegitimate child. Hearing this, Callie's sympathy for the child grows and she adopts the child. Three years later, a man appears at her doorstep, striking a resemblance to the almost three-year-old child living in her home.
