Early Frost is a 1982 Australian thriller film starring Guy Doleman, Jon Blake, Diana McLean and David Franklin.
Hayes meets David Prentice who keeps a scrapbook on violent crime and gets further information about the temperamental and schizophrenic Val Meadows, the mistress, and learns of her fears.
She has set her two sons off on a "Don't do as I do, do as I say" kind of existence, where mindless punishments are used as a substitute for love and understanding.
The wife, Peg Prentice, on the other hand, is too indulgent with her son David - accepting his disobedience - because he is the only adult in her life (her husband is constantly away on business).
[3] The number of mysterious accidents involving the deaths of all those women in suburban Australia, lead Val to suspect her son of mass-murder.
