Tarantula

A lone-wolf scientist sequestered in a mansion close to a small desert city arouses the suspicion of the city’s physician when his lab assistant is discovered lifeless from a case of acromegaly which took solely 4 days to develop. Because the physician investigates, aided by the scientist’s new, and really feminine, assistant, they uncover that, far worse, one thing a lot bigger and hungrier than it ever ought to be, is devouring native cattle – and people – in more and more giant portions.
