Queen Bee(1955)

She's so excitingly good . . . when she's so wonderfully bad!

A devilish Southern woman, married to a man who despises her, manages to manipulate those around her under the guise of being kind. But, when her sister-in-law is engaged to be married to the woman's former lover and her husband starts up an affair with her cousin, visting from New York, things start to go awry and she sets a plan to destroy it all.
