Every family member in turn finds out that they may have had a hand in her death. Mr Birling (Arthur Young) for example sacked her once from his factory for trouble making. The daughter Sheila (Eileen Moore) got her fired from her job in a store for wearing a hat better than she did. As the puzzle continues to unravel via flashbacks then so too does the supposed respectability of the Birling family...
Outwardly a simple film but full of surprises and twists (especially at the end) and so wonderfully done. Alastair Sim plays a wonderful role, he lets the store unfold around him as the hypocrisy and immorality of Edwardian England is laid bare.
