George Banks is an ordinary, middle-class man whose 21 year-old daughter Annie has decided to marry a man from an upper-class family, but George can’t think of what life would be like without his daughter. He becomes slightly insane, but his wife tries to make him happy for Annie, but when the wedding takes place at their home and a foreign wedding planner takes over the ceremony.

Just when George Banks has recovered from his daughter’s wedding, he receives the news that she’s pregnant … and that George’s wife, Nina, is expecting too. He was planning on selling their home, but that’s a plan that — like George — will have to change with the arrival of both a grandchild and a kid of his own.
