Five individuals from five nations, including the "Superpowers" (USA, USSR and China), suddenly find themselves on an alien spacecraft. An alien gives each a container holding capsules. No power on Earth can open a given container except a mental command from the person to whom it is given. Each person has been provided with the power of life and death. Any of these individuals has the capability to instantaneously launch the capsules to whatever coordinates he/she chooses, and each capsule will then eradicate all human life within a 3,000-mile radius of its designated location.

Did You Know?


This was based on a novel by John Mantley. Mantley himself wrote the screenplay. This may explain why this film is regarded as more intelligent than most low budget science fiction films of that period. See more »


When one of the capsules is tested, Dr. Neuhaus instantly disappears. This would mean that every human within the 3,000-mile radius would have suffered the same fate. There would be no way of clearing everyone out of that size area anywhere on the populated areas of the Earth. See more »


Jonathan Clark: People hate because they fear, and they fear anything they don't understand, which is almost everything.

A thoughtful look at "the 27th Day"
14 December 2001 | by scotmachighSee all my reviews

This a very thoughtful film. Even though the film takes place in 1957 the subject matter is current into todays world. The film makes you think of society as a whole. Not of just one nation. The ills and the good of human relations with each other and our surroundings. How far we would go to make this world a far better place or a Hell of earth. It makes you stop and think, what would you do with the power the people were given in the film. The effects were average for a film of the time period. Great effects were not needed though. Watch, listen and think. The film gets better each time you watch it.
