A red-gloved murderer is gouging out the eyes of American tourists. It’s up to Inspector Tudela to discover the killer’s identity and stop them before their sick game is complete.

The international success of Argento’s THE BIRD WITH THE CRYSTAL PLUMAGE (1970) ushered in the golden age of Giallo and enshrined the trope of the black-gloved killer. Lenzi directed four Gialli during this period: SEVEN BLOOD STAIND ORCHIDS (1971), KNIFE OF ICE (1972), SPASMO (1974) and EYEBALL (1975).

By 1975, the film market was oversaturated with subpar Gialli and the genre’s popularity waned. Lenzi reflected on this decline with his final Giallo, the satirical EYEBALL (1975), an intentionally low-brow film that never takes itself too seriously.
