Las Fieras (1969)

In 1989, six year old Martin Bristoll was kidnapped from his backyard swing in Minersville Pennsylvania. Graham Sutter, a psychotic recluse, kept Martin imprisoned on his derelict pig farm, forcing him to witness and participate in unspeakable horrors. Chosen at random, his victim's screams were drowned out by the rural countryside. For five years, Martin's whereabouts have remained a mystery, until 17 year old Allison Miller comes to live with her Uncle, Jonathan. While exploring her new surroundings, Allison discovers things aren't quite right at the farmhouse down the road. Her curiosity disturbs a hornet's nest of evil and despair that once torn open, can never be closed.

前作のラストで宇宙に飛び立った老人たちと異星人が、近く起きる海底地震に備えるためまだ残っている仲間の救出に帰ってきた……。

The film follows Jack Hopkins (played by Michael Craig), an aircraft designer with a passion for traction engines. His boss (played by Cecil Parker) is eager to sell a new supersonic jet plane that Jack has designed to American millionaire Paul Fisher (Alan Hale, Jr.). The first encounter between Fisher and Jack goes badly, and tensions only heighten after Fisher's daughter Kathy (Anne Helm) damages Jack's prize traction engine "The Iron Maiden", rendering it impossible to drive solo. Jack is desperate to enter the annual Woburn Abbey steam rally with the machine, but his fireman is injured and unable to participate. When all seems lost the millionaire himself is won over by Jack's plight and joins him in driving the engine; the two soon become firm friends.

Despite vocal objections from Warden Blakely, prison psychologist Diana Purlow journeys deep inside the mind of serial killer Jesse Mowat in a desperate attempt to reveal the source of his psychotic tendencies.
