There are two things worse than a mad scientist. The first is a sad scientist. The second is a whole mob of mad scientists. This film spotlights both. Our sad scientist just lost his son to a weird genetic mutation. That even also made him lose his wife and eventually his career. Now he gets a new job at some German think tank. They are interested in his research in screening genetic mutations and he's interested in finding a place to lay low and lick his wounds a bit.
Unfortunately his plan fails as he falls between a former student and a rather crazed scientist who are sort of feuding over who owns what discovery. Considering that the mad scientist (who looks like a Mr. Hugo doll on meth) is talking about infecting mosquitoes with viruses to turn people into communists it's safe to say the experiments are a little... out there. All this plus the sad scientists deteriorating mental condition leads to a rather dark if unattended experiment.
This is a good thoughtful film. Don't be put off by the slow pace. It's all a very Croenbergian affair so just let the madness wash over you like a crazed white sound generator.
