Synopsis
An escaped safecracker is delivered to a secluded operation run by a former military officer. A captive scientist can make him invisible, allowing thefts of tightly guarded nuclear materials. The arrangement promises power to his captor and freedom to the thief, but the experiment has consequences neither man can comfortably control.
