In this comedy, a grandmother decides to help her naive grandson get the money he needs to marry his girl by allowing him to get his inheritance, a mattress factory, before she dies. She suggests that he use it as collateral on a loan, but instead the young man sells the business to a crook who ends up charging another interested buyer an exorbitant interest rate for it. The angry buyer then tries to force the lad's father to buy back the factory. That doesn't work, so he ends up kidnapping the grandmother. This is not a wise move as the grandmother is far more clever than her captor and quickly turns the situation around to her advantage. Soon the kidnapper hands the factory back and gets nothing in return.
