Two couples are lured into a remote mansion where they fall victim to occult rituals, sexual debauchery, and satanic terror. Satans Blood (Escalofrío) is a notorious piece of Spanish exploitation horror, infamous for its satanic orgies, ritual sacrifice, and Euro-horror sleaze during the post-Franco era.

Its diabolical hi-jinks, gory thrills and devil dolls abound in this essential Euro-horror entry from post-Francoist Spain! When a young married couple venture out into the city of Madrid, they have a chance encounter with a mysterious couple, claiming to be old friends of theirs, who invite them back to their large, secluded villa out in the countryside. What follows is a night of bizarre satanic orgies, blood curdling nightmares and gruesome murder as the young couple are thrust into an entangled world of cabalistic ritual where their very souls may well be the next offerings to the dark prince himself! 

Carlos Puerto directs this devilishly erotic gothic chiller; a prime example of the liberated S rated run of Spanish cinematic terrors executive produced by Juan Piquer Simon (Pieces) and stacked with hellish bonus features in this much-treasured special edition!
