It all starts in Simon's (Byron Foulger) hardware store where the
hardware seems to come to life ...
Soon enough, agents Stewart (Richard Carlson) and Forbes (King Donovan)
of the OSI (Office for Scientific Investigarions) and they realize there
is something wrong witht he magnetism in this shop ... and this something
seems to originate from the lab directly above the shop, where two
scientists were experimenting on a new radioactive element. One of the
scientist is dead by now, drained of all life energy, the other (Leonard
Mudie) has the element with him, on a plane - which is even worse because
the element will quite surely eventually mess up the plane's engine due to
its magnetism ...
Fortunately, Stewart and Forbes manage to somehow ground the airplane
before anything happens, but the scientist they realize, is breathing his
last, drained of all energy ...
Stewart and Forbes experiment with the element, and soon they realize
that it actually feeds on energy, and with each feeding - which happens
every eleven hours - the element doubles its size, but also needs double
the amount of energy with the next feeding.
Soon enough, our scientist heroes realize that it is only a matter of
days before the element will need the whole earth to feed on ...
Eventually, Stewart and Forbes fly the element to a laboratory below
the ocean's surface with a generator big enough to not only feed the
element but actually choke it with energy (!). When our heroes try that,
the lab and the whole generator almost go up, but in the end, they
succeed, and once again earth is saved.
My synopsis might sound rather boring and incomprehensible, but despite
a storyline that is overconvoluted and silly at the same time, despite
dialogue that is filled up with (now outdated) techno-babble, despite a
certain dose of unintentional humour (I loved the scene best where the
machines in the hardware store camt to life) and despite the fact that the
most impressive scenes (those of the generator) were actually lifted from
another film, the German Gold from 1934 (!), this film somehow
works as a good-natured science fictioner containing plenty of action and
suspense to keep one entertained nevertheless. It's certainly no genre
classic, but it's fun ...
