Night of the lepus

Sinopse

A hormone intended to alter the breeding cycle of rabbits overrunning ranchlands instead turns them into flesh-eating, 150-pound monsters. Stuart Whitman, Janet Leigh, Rory Calhoun, and DeForest Kelley are among the intrepid humans facing the behemoth bunnies. They use guns, flames, and dynamite to subtract them. But the rampaging rabbits know how to multiply. Can anything stop these hare-y scary monsters?
