A series of animal deaths and other disasters hits a rural town. When humans start dying, a local, bewigged, stock native known, not-so-lovingly, as "Injun Joe" speaks of omens and portents. The townsfolk are... unimpressed. The sheriff is flummoxed by it all.
When archaeologist, Dr. Frederick Cleveland (the ubiquitous Morris Ankrum) and his daughter, Janet (Sally Fraser) come to town, they draw the sheriff's suspicion. Especially, since they happen to know a loner, named Wayne Brooks (Ed Kemmer).
Cleveland just happens to be searching for evidence of an ancient, sadistic, towering conquistador known as Vargas, The Devil Giant.
Coincidence? Hmmm.
Cheeeze-tacular, pseudo-scientific claptrap sets up the idea that the old behemoth could possibly have been reanimated. While Cleveland and Brooks search for artifacts, Janet makes lunch, brews coffee, and cleans up the camp!
Aaaah, the 1950's!
After what feels like a century, Vargas finally makes his appearance, but nothing much takes place. The obligatory romance blooms between Janet and Brooks. More locals are eliminated. Will the sheriff ever believe the truth? Will Janet ever brew the perfect pot of coffee? Will "Injun Joe" ever get a better hairpiece?
Cheddar doesn't get much chunkier than GIANT FROM THE UNKNOWN! Highly entertaining hooey!
P.S.- Janet also makes sandwiches...
