The storyline is unbelievable. First, one would think that a business that handles radioactive material would hire someone with more maturity and not a "kid" as Matthews called him. Secondly, one would think that such a business would train its worker on how to handle the material and the dangers associated with exposure so that the worker would be competent enough to transport the cannister and would not have misconceptions about the effects of exposure, should that happen. Third, no business like this would have just one worker, and a rather immature one at that, left alone to do the job without at least a second or third person or supervisor doing some oversight and support. At least, one would hope. Fourth, the lab worker Harry Wells (played by Leonard Nimoy) is such a bungler that he almost makes Larry, Moe, and Curley of the Three Stooges look professional by comparison.
