A scientist is nearly assassinated. In order to save him, a submarine is shrunken to microscopic size and injected into his blood stream with a small crew. Problems arise almost as soon as they enter the bloodstream.
Scientist Jan Benes, who knows the secret to keeping soldiers shrunken for an indefinite period, escapes from behind the Iron Curtain with the help of CIA agent Grant. While being transferred, their motorcade is attacked. Benes strikes his head, causing a blood clot to form in his brain. Grant is ordered to accompany a group of scientists as they are miniaturized. The crew has one hour to get in Benes's brain, remove the clot and get out. Written by

The scenes in the spacious corridors of the secret CMDF medical facility were filmed in lower and upper concourses of the Los Angeles Memorial Sports Arena. Director Richard Fleischer would later use the arena for exteriors in Soylent Green (1973). See more »
The scuba equipment has a low-pressure hose running between the tank and the face-mask. The face-mask appears to have a regulator built in (the silver disk). The regulator reduces the pressure from the tank to a pressure the diver can breathe. The typical pressure of an open SCUBA system with a regulator tank is 200-300 atmospheres. This would blow out the hose as soon as the air was turned on. See more »
This is not only a great science fiction film, it is also a great thriller as well. I especially loved the fact that this was supposedly done in "real time" and that the characters and that it was not only a mission to save the scientist life, but a race against time before the miniaturization wore off. Also, even though the effects are dated, they still were pretty good for the era they were produced in.
