The plot of "an inspector calls- involves the Birling family who are an upper middle class family of the 20th centaury. It involves a girl who is sucked form a job by Mr. Birling for organising a strike, who is later sucked from a job by Mr. Birling's daughter Sheila because she was jealous of the girl's beauty.
The same girl changes her name from Eva Smith to Daisy Renton after she has an affair with Sheila's fiancé Gerald Croft, all summer. After Gerald dumps her, she has an affair with Eric Birling, Mr. Birling's son, and she becomes pregnant. But she wouldn't get any more money from him after knowing that he stole it. So she decided to ask for help at one of the Charity Organisations where Mrs. Birling turns her down, because she first introduces herself as Mrs. Birling and this initially put Mrs. Birling off of help her.
An inspector Goole comes, who so happens to know everything about all these people, when they are having an engagement party for Sheila and Gerald. He informs them that a girl has committed suicide and gets them all to confess of their contact with the girl. After he has left they discovered that he wasn't a real inspector and that no girl has committed suicide. Just as they are trying to forget about Eva Smith and the Inspector Goole, they receive a phone call informing them of a girl who has committed suicide and that an inspector was calling at their house to investigate the case.
The non-realistic thing about this play is that all five people have had contact with exactly the same girl. The chances of their happening in reality are 2 out of 10. The other thing is how this so-called inspector Goole happens to know everything about each of the five people, even though he is not an inspector at all.
THE HISTORICAL BACKGROUND.
Mr. Birling, a typical businessman who follows typical business practices, is so certain that life will turn out his way because he made all his money by working hard.
