A magician known as The Great Schultz plans a pseudo-scientific act in which he seems able to change his wife into a rabbit and Grindl is mighty impressed.
The great bank robbery is what a group of thieves have been planning to pull but they are unable to find the bank's weak spot that is until Grindl is hired as a teller.
Grindl inherits a British estate and the title ""Lady Grindl."" She arrives at Dundstetter Moors to claim her inheritance, but three bent twigs on the family tree try to frighten her away.
Grindl meets a handsome and eligible suitor through a marriage bureau, but before the wedding takes place, the bridegroom takes out a large insurance policy on Grindl's life.
Grindl, who's working for the Hartmans, is very upset when Mrs, Hartman disappears and her suspicions mount when Mr. Hartman displays extreme sensitivity about a locked basement door.
