After a daring escape form a psychiatric hospital, The Stepfather (Terry O´Quinn- TV´s Jag) assumes a new identity and sets out in search of another family to marry into-and kill! He finds the perfect victims: attractive, recently divorced Carol Grayland (Meg Foster-The Man In The Iron Mask) and her teenage son Todd (Jonathan Brandis-Hart´s War). Posing as a warm and caring family therapist named Gene, he appears to be the ideal second husband and father for these two lonely people. But Carol´s best friend Matty (Caroline Williams-How The Grinch Stole Christmas) suspects that Gene is too good to be true. And when Carol´s first husband returns to attempt a reconciliation, he triggers Gene´s fear of discovery, sending him off on a psychotic killing spree. Gene secretly eliminates everyone who stands in his way, until the day arrives to marry Carol, one of the most unforgettable-and horrifying-wedding days ever filmed.
