The underlying premiss of this film is quite interesting. Five people are kidnapped by a vastly superior alien race and each given a potentially toxic capsule. These capsules can only be opened upon the command of the owner, but if they ever are then mankind is doomed to eradication. The five are from different nations and all walks of life and once the alien announces to the assembled world the identities of the group, their lives become frantic and unsafe - a predicament they must endure for twenty-seven days if they are to save the population from certain death! Arnold Moss does his best "Klaatu" impersonation as the visitor and William Asher offers us a considered story about how ordinary people - and their governments - might react in such weighty circumstances. Gene Barry leads a rather unimpressive cast, however, and that really lets this decent story down somewhat. He wasn't very good at the best of times, and here neither he nor Valerie French's "Eve" do justice to the intrigue of the plot. The ending, even after a few viewings, is a bit disappointing - but the whole concept makes this well worth watching.
