The Killer Shrews
(1959)

Engineered by the team of scientists, the shrews are not only flesh-eating but also poisonous. As they managed to penetrate the house, making it unsafe for the survivors, Sherman (James Best) then straps a few barrels together so they can hide under while walking to the water.

Farrell (Ken Curtis), whose jealousy about Ann (Ingrid Goude) makes him attempt twice to kill Sherman, stays with a rifle and gets eaten.

Ann, and her father, Dr Craigis (Baruch Lumet), escape with Sherman who ultimately gets the girl.
