FANTASTIC VOYAGE (Sci-Fi)

The battle being waged by the super powers is who can perfect miniaturization. Now both sides are stumped as to how to control it. So far, they can miniaturize anything, but up to sixty minutes only. Scientist Jan Benes (Jean Del Val), who is believed to have solved it, was about to give it to the Americans when an attempt is made on his life. Fortunately, he is not dead, but he is in a coma and any conventional means to operate on him could be fatal. So a plan is made to miniaturize a vessel, send a team of doctors into his body, and that they will go to the damaged area and fix it. The problem is that there is a report that someone on the team could be working for the other side. So they send C.I.A. Agent Grant (Stephen Boyd) to make sure everything goes okay.
