When the mute Martha Caldwell (Carroll Baker) discovers her famous cousin Jenny Ascot (Evelyn Stewart) has been brutally murdered, apparently by a strange man who had been stalking them, her world becomes one of nightmare and disturbing revelation.

Directed by Italian legend Umberto Lenzi, (So Sweet, So Perverse, The Cynic, the Rat and the Fist, Cannibal Ferox) Knife of Ice (1972) is a quintessential piece of early 70s Gialli creepiness. Dreamlike, brutal and beautifully presented Lenzi's movie delivers a wonderfully creative mystery replete with a typically European twist in the tail.
