Second episode of the saga of "Gamma One", where Antonio Margheriti uses the same actors of "Wild, Wild Planet", Tony Russell, Lisa Gastoni and Franco Nero. The story narrates again of an alien menace, but this time the danger is represented by incorporeal creatures, made out of light and energy, diaphanous, that's why are called "Diaphanoids". 

The Diaphanoids get possess of the body of all the humans who comes at their range, controlling their will. An atmosphere near to an horror film characterizes this movie filled with scenes rich of tension and fears, accentuates by a persistent and obsessive music.

Curiosity

This film was destined to become famous starting from the title, which would have inspired the poet Allen Ginsberg while he was travel from Florence to Milan, and stopping by San Gimigniano would have noticed the posters of Antonio Margheriti's film. Arrived in Milan, he would have added to his poetry "Pentagon Exorcism" a significant verse: "...Physical slavery to diaphanoid chinese cosmic-eye Militar Tyranny...".
