Trillionaire Liam believes he has found the perfect psychological-rehabilitator fiancée Vanessa for his five-year-old daughter Mia, who suffers from traumatic mutism. But what he doesn't know is that Vanessa is a two-faced demon — she not only cruelly abuses Mia in secret, hacking off her hair, but is also pregnant with a bastard child by her secret lover Mark, and plotting to slowly poison Mia to death in order to seize the billionaire's five-hundred-million-dollar trust fund! Brave little Mia grits her teeth through the torment and, using an old toy watch with a dead battery, secretly records the murderous plan of the scumbag and vile woman. When Liam hears the recording in his study late at night, his world collapses — and a storm of fury follows!
