Young Katy Collins (Conner) is one of a kind: a demonic child orchestrated by an evil corporation managed by Dr. Walker (Mel Ferrer).

After her mother Barbara (Nail) refuses to give Katy an equally demented sibling, it's up to space emissary Huston to call in the 'good' visitors from beyond to save the day.

Turns out said alien peacemakers are bald children who can morph into vicious doves, an ensemble led by Christ-like Franco Nero.

This totally offbeat - but surprisingly well made - Italian oddity boasts an all name cast and kind of a cool sparse vibe, but is sooooo strange.

Best scene: Ford's (too early) death at the bloody beak of a psychotic bird.

Also known as Stridulum.

Italian: Il Visitatore.
