Build a movie plot around this: Who strikes again and again? The unseen enemy
We open with closeup of a syringe and Dr. Kirby (an uncredited Aline Towne) injecting a solution into a lab monkey, Pepe. He is wired up for an experiment in freezing and thawing. Through the window we see Dr. Hubertus (Michael Fox), the department head. The chamber is reduced in temperature to minus 85 degrees and Pepe is frozen solid in less than two minutes. The process is reversed and Pepe is revived. The test is deemed a success. Pepe is sent to the lab for a blood count, and Dr. Hubertus sends Dr. Kirby to the supply room for a more sensitive thermostat. After Dr. Kirby leaves, the cold chamber door closes, trapping Hubertus. He struggles to get out as the automated equipment begins its deep cold cycle. Hubertus is frozen solid. Dr. Kirby finds the thermostat and returns to the cryo lab. She enters the chamber to discover the dead and shattered remains of Dr. Hubertus. The door closes on her and the cryo cycle repeats, killing her.A helicopter crosses the desert sky. On board is the pilot Al (an uncredited Al Bayer) and his passenger, Dr. David Sheppard (Richard Egan). They are headed for the satellite project, a top secret facility built underground. The helicopter is suddenly tossed around, much to Sheppards concern, but the pilot explains that the "brain" has taken over the controls and will do the flying. It keeps the exact location of the facility secret. The pair are being monitored by central control. Just before they land the sun mirror shines on them.After landing, Dr. Sheppard is met by two security guards, Andy (an uncredited Andy Andrews) and Julie (an uncredited Julian Ludwig). They ask for and verify Dr. Sheppards credentials. Cleared for entry, Julie escorts Sheppard in the elevator to Dr. Van Ness' office. Dr. Van Ness (Herbert Marshall) greets Sheppard and unlocks the brief case he has manacled to his wrist. Sheppard presents his orders and is told he was specifically requested because the project is in jeopardy, and Van Ness has "positive proof of a saboteur on my staff." He calls his...
