The Locked Room

When Davey Snowden marries wealthy (but homely) Bonnie Daniels, he anticipates moving into her family’s mansion and recovering the fortune he imagines lies in a tightly locked room. Stymied by Bonnie’s formidable mother, he plays a trick which not only causes him to lose both Bonnie and her fortune, but to realize only too late that his mother-in-law is not through with him yet.

A newlywed woman's mother believes her plain daughter's husband only married her for money, so the mother plots a cruel scheme against him.

The bride's mother plays villain in the life of a newly wed couple. She is convinced the boy has married her not-too-beautiful daughter simply for her wealth and plans a nasty surprise for him.
