Blood Child is horror thriller based on a true story. Bill and Ashely DiAngelo seem to have it all, an overseas posting to Singapore, life in paradise and a new baby on the way. But tragedy strikes when she loses the baby and sinks into a deep depression.
Unbeknownst to Bill, Ashley decides that the only way for her to "be" with her miscarried child is to dabble in the South East Asian occult practice of raising her own "ghost child". She seeks the help of her Indonesian maid, Siti, tasking her to find a bomoh (witch doctor) who knows how to trap the spirit of unborn dead fetuses. Siti tries to dissuade Ashley from resorting to such dark magic but to no avail.
In the meantime, in an effort to put the tragic events of the miscarriage behind them, Bill decides that it would be good for the couple to return home to Minnesota to start their lives over. Several months after their return to the US, Ashley and Bill are surprised to find themselves pregnant again. However, their happiness is short lived as the pregnancy acts as a catalyst for a series of terrifying events that start to occur within the DiAngelo's home.
Bill, Renee (Ashley's mother), and Naomi (Ashley's best friend) soon learn that Ashley has brought back a lot more than just memories from Asia, and that Siti is helping Ashley with more than just the housework. Ashley's ghost child, Anna, is not about to play second fiddle to the impending new arrival, and unleashes an unspeakable evil upon everyone.
