This film is mainly just a lot of conversation about a secret formula which the audience finds out later apparently called sterility in women, particularly over in Africa. Kenneth Haigh spends most of the time either conversing with his wife or two young female hitchhikers he picks up, and finally having a confrontation with Harry Andrews where the big secret is revealed. There's some suspense in the opening scene where a man in a bowler hat enters a city park, passes by a homeless woman on a bench, sneers at her and walks on. Later it is revealed that he has been found dead, and there is debate over whether it was suicide or murder.

The only memorable moment for me was the scene with the hitchhikers in the car marveling over the fact that he had a car phone, and the one girl using it to call her mother who finds the idea of the invention absurd. While the setup indicates that there is going to be some intrigued, there are only little tidbits of it here and there, and Haigh (who is apparently the successor to the dead man's post at the company where this formula was created) debates the value of this creation on society. It's a very boring film outside of the conversation with the young girls and Haigh (which frankly goes on a bit too long and serves no plot purpose), and all I could think of as the film ended with a doll resolution was what did I just waste my time on?
