Synopsis: A maniacal killer commits savage acts of slaughter and the only key to the perpetrator's identity and motive is the puzzle of the half-moon lockets! Can the mystery be solved before the killer cold-bloodedly claims his intended seven victims?
Based on the nerve-shattering, acclaimed novel by Edgar Wallace (King Kong) and starring Uschi Glas (College Girl Murders), Antonio Sabato(Barbarella, Escape from the Bronx) and the stunning Marisa Mell (Danger Diabolik), come a stylish, crimson-dripping giallo from cult director Umberto Lenzi (Make Them Die Slowly, Spasmo).
