Best Defense

An ironic aspect of this otherwise indigestible flop is that the final concept, although created as a desperate, expos facto attempt to inject life into the film, might have actually worked, had it been in the plan from the beginning.

Although the future plot line (or present, according to how you wish to perceive it) involving Murphy was filmed later, the concept of one plot line's actions having a direct result on another in the future could have been interesting. All it needed was a script, production values, creative foresight and inspired performances by the actors. This film, unfortunately, had none of the above.

Moore is convinced that a device slated to be installed on a tank is defective in its design, and must try to fix it before it's built and put into use. Two years in the future, sure enough, Murphy is driving a tank which uses this very device. Will Moore improve the design in time to save Murphy's life? Well, it's little confusing to flash back and forth between these plot lines, but they do manage to culminate into a semi-climactic moment, but much too late to save the viewer from mindless boredom.
