The Premonition (1975)

A young girl who's terrified her insane (birth) mother will take her away from her beloved foster mother. One day, when the birth mother attempts to contact the girl at school, but her foster mother has a premonition and gets there, just in time to protect the girl. Eventually, the real mother and her boy friend (a carnival clown), do exactly what the girl feared; they takes her away, leaving the bereaved foster parents to enlist the aid of a parapsychologist to help them understand terrifying dreams they've had, and find the girl before it's too late.
