Marie Windsor plays a detestable woman so no one knows who killed her, because they all could have.
There is one major plot point that doesn't make any sense. As awful as character Windsor is, she wouldn't bother going after her best friend and partner's poor boyfriend. It is not explicable in any way. He is not her type. If she needed a date, she could have asked Patrick Knoles, the Wayne Vincent character.
But even with that flaw, the film has great forward movement and Windsor is so good at being awful the plot works.
John Archer plays the husband who wants a divorce. Nancy Gates is the woman he wants to marry. Jill Jarsijn is her best friend.
All in all it is a fun film directed by Franklin Adreon and written by Ron Martin.
