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), comes a stylish, crimson-dripping giallo from cult director Umberto Lenzi (MAKE THEM DIE SLOWLY, SPASMO).
