The Five Mrs. Buchanans

A Ring of Truth (1x4)

:

When Bree receives a belated engagement ring from Jesse, she's ecstatic -- until she learns that it's not a real stone. One by one, each of the sisters-in-law come to realize that their rings aren't real either. The husbands are on a fishing trip together and can't be reached, but when they reveal the secret of their rings to Mother Buchanan, she makes a revelation of her own.
